My question is related to medication for afib. I have been on warfarin for approximately four years with an intervention period of 4 to 5 months. I am experiencing pain that started in the outer half of my right thigh and now is including my right calf. I am concerned that it may be an effect of the warfarin. I also have a lot of arthritis and possibly fibromyalgia. I am diabetic and have moderate kidney diasease with Hbp.. I have mentioned this pain several times to my Primary physician and he sent me to the rheumatologist with no help there. What should be my next step? Also is this a side effect from the Warfarin?
