I've had wrist pain for around 6 months. I experience pain in my thumb, can't grip anything, move my wrist and constantly wear a splint. I have muscle wasting in my hand and arm. Nerve conduction test came back clear, bloods came positive for rheumatoid factor. Im awaiting mri arthrogram results. I am pain the majority of the day and find the one thing which receives the pain is heat. My job doesn't allow this all day as I work in admin, quite a lot of paperwork involved. Im worried I may have arthritis but I don't experience flare ups, I have pain every day. The consultant feels if not rheumatoid arthritis it could be due to one of the bones in my arm being shorter than the other due to a fracture in 1997. Does anyone have any advice?
