Only speaking from experience here, I have felt a similer pain. I have
bad shoulders, surgery on one for torn rotator cuff and being that i
have issues with them, I unconsciously was tensing and carry that side
differently. I would get the worse pain in and between my
shoulder/neck. After numerous x-rays I finally went to and sports
medicine Dr who did an MRI and diagnosed it so you may want so try that.
Good Luck!
