NECK AND SHOULDER DISCOMFORT
Trigger points can be found in taut bands in the muscles on the sides and
back of the neck and upper back region. There are many muscles that
originate in the head and neck and extend to different muscles in the rest of
the body. When these muscles have been injured or overused, they can
result in general soreness, stiffness, fatigue and/or headaches.
