Dr. Daniel Lee Grotzinger was born in St. Marys, PA on July 7, 1948. He grew up with a deep interest in music and aviation. In his senior year he applied to both the Air Force Academy and for a Pitt university music scholarship. Neither came through. A semester was spent at St. Vincent college in Latrobe, PA studying for the Catholic priesthood before deciding to enlist in the USAF during the Viet-Nam war. He specialized in the radar systems for the B-58 and B-52. After four years of service he was discharged with spinal injuries. Several years of severe back pain with sciatica, with no relief from the usual medical methods lead to Dan trying chiropractic upon the advise of a church friend. In three visits the severe bilateral sciatic pain was resolved. Again, he applied to music school but found there was a long waiting list. Because of the tremendous help chiropractic had given him he began to think there must be a lot of others who have gone through what he did and could use the same kind of help. After several prayer sessions he received a very clear witness that this should be his life calling.
Low back pain. A 2013 Cochrane review found very low to moderate evidence that SMT was no more effective than inert interventions, sham SMT or as an adjunct therapy for acute low back pain.[94] The same review found that SMT appears to be no better than other recommended therapies.[94] A 2016 review found moderate evidence indicating that chiropractic care seems to be effective as physical therapy for low back pain.[95] A 2012 overview of systematic reviews found that collectively, SM failed to show it is an effective intervention for pain.[96] A 2011 Cochrane review found strong evidence that suggests there is no clinically meaningful difference between SMT and other treatments for reducing pain and improving function for chronic low back pain.[97] A 2010 Cochrane review found no current evidence to support or refute a clinically significant difference between the effects of combined chiropractic interventions and other interventions for chronic or mixed duration low back pain.[98] A 2010 systematic review found that most studies suggest SMT achieves equivalent or superior improvement in pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up.[99] Specific guidelines concerning the treatment of nonspecific (i.e., unknown cause) low back pain are inconsistent between countries.[100]

Attached to the back of each vertebral body is an arch of bone that forms a continuous hollow longitudinal space, which runs the whole length of the back. This space, called the spinal canal, is the area through which the spinal cord and nerve bundles pass. The spinal cord is bathed in cerebrospinal fluid (CSF) and surrounded by three protective layers called the meninges (dura, arachnoid and pia mater).


In the U.S., chiropractic schools are accredited through the Council on Chiropractic Education (CCE) while the General Chiropractic Council (GCC) is the statutory governmental body responsible for the regulation of chiropractic in the UK.[176][177] The U.S. CCE requires a mixing curriculum, which means a straight-educated chiropractor may not be eligible for licensing in states requiring CCE accreditation.[65] CCEs in the U.S., Canada, Australia and Europe have joined to form CCE-International (CCE-I) as a model of accreditation standards with the goal of having credentials portable internationally.[178] Today, there are 18 accredited Doctor of Chiropractic programs in the U.S.,[179] 2 in Canada,[180] 6 in Australasia,[181] and 5 in Europe.[182] All but one of the chiropractic colleges in the U.S. are privately funded, but in several other countries they are in government-sponsored universities and colleges.[25] Of the two chiropractic colleges in Canada, one is publicly funded (UQTR) and one is privately funded (CMCC). In 2005, CMCC was granted the privilege of offering a professional health care degree under the Post-secondary Education Choice and Excellence Act, which sets the program within the hierarchy of education in Canada as comparable to that of other primary contact health care professions such as medicine, dentistry and optometry.[169][170]

Check all that apply. Most people will not be able to check many of these! But the more you can check, the more worthwhile it is to ask your doctor if it’s possible that there’s something more serious going on than just neck pain. Most people who check off an item or two will turn out not to have an ominous health issue. But red flags are reasons to check… not reasons to worry.
One of the most common causes of neck pain is a pillow that is too large or too flat. Make sure that the pillow you use adequately supports your neck without causing any excessive bending. In other words, if lying on your back, your neck should not be bent unduly upwards. lf lying on your side, your neck should not be bent up or down (i.e. your spine should be in a straight line). Sleeping on your stomach with your neck twisted or bent to the side can also result in neck pain.

What is so good about an apple? Is it the color, ranging from ruby red to pale pink? Is it the crunch? The sweetness? Or is it, instead, a combination of all of these qualities, plus the natural goodness derived from the apple's secret ingredients — phytonutrients? If this were a multiple choice quiz, the answer would be "all of the above". Importantly, in addition to possessing numerous appealing physical qualities, apples contain an abundance of health-promoting biochemicals known as phytonutrients.1,2 These specific organic molecules are derived not only from apples but many other fresh fruits and vegetables, and help power the immune system, protect against cancer, maintain healthy eyes, and assist cells in clearing out metabolic waste products such as free radicals. ...

Twenty‐six to 71% of the adult population can recall experiencing an episode of neck pain or stiffness in their lifetime. Neck pain is more common in females than in males, with rates reported as high as 77.8%. The natural history is unclear. Neck pain has a costly impact on society because of visits to healthcare providers, sick leave, disability and loss of productivity. There are a number of treatments available for neck pain, one of which is mechanical traction.
The disk acts as a shock absorber between the bones in the neck. In cervical disk degeneration (which typically occurs in people age 40 years and older), the normal gelatin-like center of the disk degenerates and the space between the vertebrae narrows. As the disk space narrows, added stress is applied to the joints of the spine causing further wear and degenerative disease. The cervical disk may also protrude and put pressure on the spinal cord or nerve roots when the rim of the disk weakens. This is known as a herniated cervical disk.

Whiplash and other neck pain. There is no consensus on the effectiveness of manual therapies for neck pain.[104] A 2013 systematic review found that the data suggests that there are minimal short- and long-term treatment differences when comparing manipulation or mobilization of the cervical spine to physical therapy or exercise for neck pain improvement.[105] A 2013 systematic review found that although there is insufficient evidence that thoracic SM is more effective than other treatments, it is a suitable intervention to treat some patients with non-specific neck pain.[106] A 2011 systematic review found that thoracic SM may offer short-term improvement for the treatment of acute or subacute mechanical neck pain; although the body of literature is still weak.[107] A 2010 Cochrane review found low quality evidence that suggests cervical manipulation may offer better short-term pain relief than a control for neck pain, and moderate evidence that cervical manipulation and mobilization produced similar effects on pain, function and patient satisfaction.[108] A 2010 systematic review found low level evidence that suggests chiropractic care improves cervical range of motion and pain in the management of whiplash.[109]
Through manual manipulation of the spine delivered to the highest standards by licensed chiropractors, chiropractic care works to restore and maintain proper communication from your brain to your body by relieving what chiropractors refer to as a subluxation, or a misalignment, of the spine. Restoring proper alignment to the spine can assist with pain relief and prevention of:

There is a wide range of ways to measure treatment outcomes.[91] Chiropractic care, like all medical treatment, benefits from the placebo response.[92] It is difficult to construct a trustworthy placebo for clinical trials of spinal manipulative therapy (SMT), as experts often disagree about whether a proposed placebo actually has no effect.[93] The efficacy of maintenance care in chiropractic is unknown.[12]

Chronic neck pain is pain, stiffness, and soreness in the neck, perhaps with decreased mobility, that lasts more than several weeks. The traditional medical response to neck pain is to recommend pain relievers, but drugs simply mask the symptoms – and taking them for an indefinite period can do more harm than good. Treating chronic pain through traditional means (including pain management, injections, chiropractic manipulation, and surgery) is not likely to resolve the true source of the pain.

Your neck is a complex interlocking structure consisting of bones, joints, nerves, muscles, tendons and ligaments. Its main job is to hold up the weight of your head which, at around 5 kilograms, is no mean task. Add to this the requirement that the head must be able to move from side to side and up and down (and do these simultaneously), plus the fact that the neck has to form a conduit for the spinal cord, carry blood vessels to and from the head, and contain passageways for air and food, and you have quite a complex feat of engineering. No wonder then that our necks cause us pain and discomfort, not only on occasion, but for some people in an ongoing fashion.The main physical structures in the neck are the seven interlocking vertebrae. They are called the cervical vertebrae, numbered C1 through to C7. C1, also known as the atlas, is the closest one to your head, followed by C2, which is also known as the axis. Each vertebra is connected to the next by facet joints, and between the vertebrae are intervertebral discs — rubbery cushions made mostly of cartilage that act as shock-absorbers.When should I seek immediate medical treatment for neck pain?Severe neck pain that occurs after a neck injury can be a serious problem, and you should see your doctor immediately. Also, if you have problems with neck pain and experience symptoms such as loss of bladder or bowel control, shooting pains, numbness, tingling, or weakness in the arms or legs, especially if these symptoms come on suddenly or get worse quickly, you should see your doctor straight away.Neck pain and stiffness that’s associated with headache and fever can be a sign of meningitis (an infection of the membranes surrounding your brain and spinal cord). Meningitis is a serious disease, and you should seek immediate medical treatment if you or your child are experiencing these symptoms.Symptoms of neck painSymptoms of neck pain and the sensations you feel can help your doctor to diagnose the cause. Here are some symptoms.Muscle spasmA spasm is a sudden, powerful, involuntary contraction of muscles. The muscles feel painful, stiff and knotted. If you have neck muscle spasms, you may not be able to move your neck — sometimes people call it a crick in the neck. Your doctor or physiotherapist may call it acute torticollis or wry neck.Muscle acheThe neck muscles are sore and may have hard knots (trigger points) that are tender to touch. Pain is often felt up the middle of the back of the neck, or it may ache on one side only.StiffnessThe neck muscles are tight and if you spend too long in one position they feel even tighter. Neck stiffness can make it difficult or painful to move your neck.Nerve painPain from the neck can radiate down the arms, and sometimes, the legs. You may feel a sensation of pins and needles or tingling in your arms, which can be accompanied by numbness, burning or weakness. This pain is typically worse at night.HeadachesHeadaches are common in conjunction with neck problems. They are usually a dull aching type of headache, rather than sharp pain. While the headaches are often felt at the back of the head, the pain may also radiate to the sides, and even the front of the head.Reduced range of motionIf you can’t turn your head to the side to the same degree towards each shoulder, or you feel limited in how far forward you can lower your head to your chest, or how far you can tilt your head back, you may have reduced range of motion. Your doctor will be able to test this.Common causes of neck painWhiplashThis commonly follows a car accident in which the person’s car is hit from behind while it is stationary or slowing down. The person’s head is first thrown backwards and then when their body stops moving, the head is thrust forward. This type of injury can strain your neck muscles and cause ligaments in the neck to stretch or tear.The pain from whiplash, which is usually worse with movement, does not always start immediately — it may take several days to come on. Neck pain and stiffness may be accompanied by muscle spasm, dizziness, headaches, nerve pain and shoulder pain.Muscle strainOngoing overuse of your neck muscles (which can be caused by a poor neck position during everyday activities, particularly computer work) can trigger neck muscle strain, causing chronic neck pain and stiffness. The pain is often worse with movement and may be associated with headaches, muscle spasms and restriction of neck movements.Degenerative disc diseaseAs we grow older, the soft gelatinous centre of the shock-absorbing discs in our spines dries out. This causes the discs to become narrowed, and the distance between the vertebrae to decrease.Herniated discIf the tough outside layer of one of the cervical discs tears, the soft gelatinous centre may bulge outwards — this is known as a herniated disc. Herniated discs can put pressure on nerve roots as they leave the spinal cord, causing pain in the neck as well as pain, numbness and weakness in the arms.Cervical spondylosisThis degenerative condition of the cervical spine is due to normal ageing and wear and tear on the cervical discs and the vertebrae. It is also known as cervical osteoarthritis, and is more common among older people.The development of bone spurs often accompanies this degeneration of the spine. Bone spurs, also known as osteophytes, are small outgrowths of bone tissue that are formed when the cartilage covering bone is worn away and bone starts to rub on adjacent bone. The bone spur is the body’s attempt to protect the bone surface. Unfortunately, the bone spur can sometimes pinch or press upon the nerve roots as they leave the spinal canal.Symptoms associated with cervical spondylosis include neck pain and stiffness that often improves with rest. The pain may radiate to the shoulders or between the shoulder blades. If there is nerve root compression, there may be numbness, pain or weakness in the arms.Cervical spinal canal stenosisDegenerative changes in the vertebrae can lead to narrowing of the canal in which your spinal cord lies — this is known as cervical spinal canal stenosis. As the canal becomes narrower, it can put pressure on the spinal cord. The associated neck pain is usually worse with activity, and may radiate to the arms or legs. Arm or leg weakness can also occur. Sometimes people with cervical spinal canal stenosis have no symptoms. Occasionally, it may give rise to Lhermitte's sign — an electric shock-like feeling down the body when the neck is bent forward.Tests and diagnosisYour doctor may be able to determine the cause of your neck pain from your history and physical examination, but sometimes tests such as X-rays, MRI scans and CT scans are required to find the exact cause of your symptoms. These scans can assess the spine and be used to show disc problems, spinal cord problems or compression of your nerve roots.Sometimes doctors will order electromyography (EMG) or nerve conduction studies — tests that evaluate the electrical activity in nerves and muscles to help determine if there is any nerve damage related to your neck problems.It can be difficult to identify the precise source of neck pain even after investigations. Generally, X-ray abnormalities do not correlate well with pain. Some people have severe spondylosis on X-rays, but have no pain. The key thing that your doctor should be able to tell is if the pain is involving pressure on the nerve roots or spinal cord. Last Reviewed: 18 December 2012

The neck supports the full weight of the head and is very susceptible to muscle strain and the misalignment of, or damage to, the vertebra in the spinal column. Almost everyone experiences neck pain at some time. These pains can be simple, which disappear after a few days, or they can be chronic. Chronic neck pain is defined as pain that persists for 3 months or more.

Chiropractic care can be an essential part of a pain management plan. By working closely with your pain specialist or primary care doctor, a chiropractor can help you realign your spine to support a strong, healthy body. One of the most difficult parts of receiving chiropractic care, however, is locating a really great and well-qualified chiropractor near you. This can be daunting. Simply going online to find a list of names doesn’t help you to know if the chiropractor you choose is going to work for you, right? There are some easy steps to take, however, when asking “how to find a chiropractor near me?” And by taking these steps, we promise you can find a chiropractor who can help you relieve your pain and get back to your life.
Sharp, shooting pains are mostly neurological false alarms about relatively trivial musculoskeletal troubles: your brain reacting over-protectively to real-but-trivial irritations in and around the spine. The brain takes these much more seriously than it really needs to, but evolution has honed us to be oversensitive in this way. That’s not to say that the brain is always over-reacting, but it usually is. Most of the time, a sharp pain is a warning you can ignore.

Employment of chiropractors is projected to grow 12 percent from 2016 to 2026, faster than the average for all occupations. People across all age groups are increasingly becoming interested in integrative or complementary healthcare as a way to treat pain and improve overall wellness. Chiropractic care is appealing to patients because chiropractors use nonsurgical methods of treatment and do not prescribe drugs.
One of the most common questions that people ask is around the safety of chiropractic care. So, how safe is it? According to the American Chiropractic Association, “Chiropractic is widely recognized as one of the safest drug-free, non-invasive therapies available for the treatment of back pain, neck pain, joint pain of the arms or legs, headaches, and other neuromusculoskeletal complaints.” While chiropractic is considered a safe complementary therapy, there can be some potential side effects, like soreness following a spinal manipulation.
