I have small painful knots in the upper/back of my neck that feel like they are on the muscle/tendons location. my systems are as fallow. 1-mind grain headaches. 2-sharp left eye pain,and eructation. 3-pain in middle back between shoulder blades. 4-left ear pains. 5-sore neck. 6-easily get mad.
I have something like that in my upper back. They sound like they could be myofascial trigger points. Have you ever tried myofascial massage? I've been able to relieve my shoulder pain by self message and by putting a tennis ball in a sock and then rolling it against my back against a wall. The goal was to increase circulation in the area and try to dissolve those tight spots. Its taken awhile but it's been quite helpful.
