Thanks for replying, Leed and madisgram. I've seen two doctors and four different physiotherapists, and carpal tunnel is actually one of the few things they haven't mentioned - tendonitis, scar tissue round my elbow and inflammation in my wrists have all been suggested, although inflammation was ruled out after the blood tests. I have an orthopaedics appointment coming up at some point, but I don't know how long I'm going to have to wait for that. Feels like I've just about exhausted all my options, my last physiotherapist basically just gave up because I wasn't improving at all.
