ABOUT THIS CASE FILE
Several weeks ago I noticed this white lump under my thumb nail. It feels like there is another one coming behind it. I can’t tell of the nail is growing over it or if it is moving down the nail. It’s goes all the way across my nail. I’ve had carpal tunnel surgery on both and a few months ago I had a cortisone shot in my thumb joint fir arthritis pain. I am prone to ganglion cyst, I wonder is that is what this is? I can not find anything about this problem online, no pictures or answers. See pictures. My thumb is also more crooked now and I notice a new knot on my thumb middle joint. I’ve had a ganglion cyst removed from this wrist many year ago, now they pop up and go away.
