i'm 18, female, work in retail. My left wrist has been hurting on and off for the past 4 years. It flares up usually after working a busy day at work (i'm right handed), the pain is in the centre of my wrist and is sometimes accompanied by pain on the top of my shoulder and shoulder blade, I've found this is possibly linked with the ulner nerve as I get a sharp pain in my shoulder blade like a pinched nerve and occasionally numbness in the fingers connected to the ulner nerve. the pain flares up every few months and can get to the point where I cant move my wrist. Do you have any idea what this could be? I've been to a specialist but he couldn't find anything definite, got an mri done, he said there was possible tendinitis but that there was nothing that could be done and I just had to deal with it. Just wanting a second opinion on this, thanks.
