Hi there I have just been told that the doctor thinks that I have a ganglion in my wrist, I have had wrist pain in my wrsist for the passed 3 years only ever since I had a car crash before that I have never had any problems, do you think this was the cause.

The car crash may not be the underlying cause of the ganglion. They, yes they, are usually an early sign of arthritis, and possibly rheumatoid arthrits. Ganglion can rupture by themselves, they are filled with a jelly like substance, or they can be aspirated by your doctor.
