This is a painful and debilitating problem because it affects everything you do. The loss of function and difficulty in doing the simplest of tasks can be very frustrating. However, there is much we can do.
Treatment for arthritis (both rheumatoid and osteo) usually involves regaining or maintaining range of movement and strengthening the muscles of the wrist and hand to better support your joints. This would potentially be a mixture of manual treatment and exercises.
Specialist splints can also be made/advised.
In severe cases, a referral for investigations or to an upper limb consultant can be made
