You don't say what other symptoms you have? I know I have enlarged wrist bones but they only bother me sometimes. I have resting splints and working splints made for me by the Occupational therapy department and they really help when my wrists are sore.
I have been really good lately and keep up my wrist movement exercises to stop them stiffening up and keep their mobility.
Are your wrists sore or is it just one wrist? I have been told to change tasks often so I don't overuse them. And carry bags etc with my arms rather than my hands, my knuckles are also swollen, as some finger joints.
Do you have RA?
Give us some more info and we may be able to help. golitho
