I have had VERY swollen fingers knuckles and wrists for several months now and they are really painful. I have seen my doctor and been prescribed both Voltarol medication and Gell to apply directly. Neither of those treatments worked and so I was prescribed Codine to help with the pain, and was sent to hospital for x rays. I was then referred to a Rhumatology clininc where I have been today. They have now refered me to a specialist Rhumatologist and also to go for Physio thereapy as they just dont know whats causing it. Can Fibromyalgia cause this? I have had fibro for 12 years now but never had this problem before.
