I also have to mention. In April when I began having the shoulder issues.. I got a couple of massages. My muscles were incredibly tight. The massage was PAINFUL. the therapist even said after the session.."You're muscles are tightening again...I've never seen that before. That's strange." My latest massage was about a month ago and wasn't as painful. The therapist said my muscles seemed a little less tense. I cut some of the gluten and dairy out of my diet and I was seeing the chiropractor. Has anyone experienced this problem with b12 deficiency?
