Do you have full range of motion?
If your range of motion is normal, even if it hurt some you need physical therapy on the wrist and arm. Sorry I don't know physical therapy much but generally light weight exercise, and I mean light weight, to strengthen and stretch gently, over time will resolve a lot of issues. Do a search for physical therapy for the wrist and see what you find. Maybe youtube will have some videos.
Please be advised
I advocate all health blogs linked to NMT.
Read them and explore MMS and CS.
It may be the best chance that you have to heal yourself
of long term and chronic illness.
