About two weeks ago I started feeling a burning in my right hand around the palm and fingers. There was also a tingling feeling like it was falling asleep. The burning increased as the day went on and ended up traveling up my arm. I tried ice...anti-inflammatory (for my RA) and it didn t help. Pain was at a level 9-10 until I used Arnica gel. That reduced it enough that I didn t go to the emergency room. Could this be from my RA or what else can it be?
