Denervation Supersensitivity |
|
When a nerve is irritated or it's supply of nutrients disrupted, it can
become overly sensitive. The muscles attached to it can become tight and
filled with trigger points. This phenomenon occurs because the receptors
in the nerve and muscle get deprived of their chemical signals and start
to make themselves more sensitive to any signal. A good example is walking
out into broad day light after being in a movie theater. While in the
movie theater, the receptors in the eyes become overly sensitive to light
in an attempt to adjust to the new environment. However, when they get
bombarded with the light of day, they get overloaded, causing their owner
to sense pain and confusion (a "white out"). The muscles and nerves react
in the same way. When a nerve is compressed or irritated in the neck, the
skin innervated by that area and the muscles attached to that nerve can
become hyper-sensitive to any stimulus.
