The joint on my middle finger below the nail has a lump that has a couple of spots that look like blisters. It dosen't hurt but is disfigureing ny fingernail. I heard it a type of arthritis. Does somebody know what it is called.
Could they be warts? That's a common spot for them and they will cause the fingernail to grow funny. If they haven't gone away, get them checked out with a dermatologist. They should be easy to remove.
It does sound more like some type of wart. Are the blisters filled with fluid?
I am getting the bumps (or lumps) in my joints below my fingers and this is arthritic in nature, but I don't have any blisters.
