Recently I have been getting this dull ache on the left side of my chest. There is no tightness and my heart is all sweet but sometimes when just leaning forward I got this dull ache. Today I was doing shoulder press and the ache was there and then suddenly something triggered in there, didn't feel like a tear or anything but couldn't lift anything after I felt the pain come on. I had a shower and could barely get my shirt over my head. There isn't any muscle soreness and when I massage the area nothing is sore to touch but find when twisting my neck around the pain seems to increase. Am thinking some kind of nerve damage or inflammation of some sort.
