I have these painful lumps on my fingers that appear after injury to the finger, I have 3 in total. Only one of them is really painful however, the other 2 don't bother me much.
The location on the lumps is on the dip joint, result of fingers getting caught in the gi during judo practice.
The big thing here is, it doesn't show up on an xray. Comparing to images of herberden nodes i would say it is really similar. Can be seen on the finger but not by xray.
Things that I have discarded already
Gout- Tests show normal
Rheumatoid factor- was 8 a few years ago and it's about 13 now, 14 would be the reference range.
Cysts- they feel hard, almost calcium like and can't really be pressed down.
-I'm just scratching my head at this whole situation, have been to rheumatologist and hand surgeon. I asked if maybe a biopsy could be taken, he said that was not possible.
