"Physiologists divide nerve-fibers, which form the nerves, into two classes, afferent and efferent. Impressions are made on the peripheral afferent fiber-endings; these create sensations that are transmitted to the center of the nervous system. Efferent nerve-fibers carry impulses out from the center to their endings. Most of these go to muscles and are therefore called motor impulses; some are secretory and enter glands; a portion are inhibitory, their function being to restrain secretion. Thus, nerves carry impulses outward and sensations inward. The activity of these nerves, or rather their fibers, may become excited or allayed by impingement, the result being a modification of functionality – too much or not enough action – which is disease."
Self care: Neck pain often resolves with rest, ice or heat, massage, pain relievers, and gentle stretches. Reduce muscle inflammation and pain using an ice pack for 20 minutes several times a day during the first 48 to 72 hours. Thereafter, a warm shower or heating pad on low setting may be added to relax the muscles. A short period of bed rest is okay, but more than a couple of days does more harm than good. If self-care treatments aren't working within the first couple of days, see your doctor.
