Has anyone ever developed bumps on their index finger? About 2 months ago I noticed a bump on my left index finger. I went to a hand doctor and he first injected it with cordisone to see if it would go away. The bump is in the inside of my first knuckle and painful. The shot didn't work at all so we decided to remove it and do a biopsy. The biopsy came back a Ganglion Cyst and not Sarcoidosis which that's what I thought it was. So about 1 month later 2 more bumps appeared on the same finger but different areas. I went to the hand doc yesterday and he said it probably isn't the Ganglion Cyst because he has never seen Cyst come back like that in a month so he said to go talk to my Rummy and see what he suggest. I have been off prednisone since Feb of this year and I'm weaning off Methotrexate now down to 7.5mg a week. I just would like anyone's thoughts one this to what you think it could be. I'm wondering if it my Sarcoid flaring up again?
