What causes warts to grow on the corner of my fingernails?
Both of my thumbs have had noticeably-sized warts on them for six months now, and smaller ones are beginning to appear on my left middle finger. . . Why is this happening?
Disregard the first two answers
Warts are caused by a virus (the human papilloma virus or HPV) that gets into your skin cells causing them to multiply more rapidly than normal. This is what causes the wart which is really an overgrowth of cells or benign tumor.
Anyway, the reason they are popping up near your fingernails is that the virus gets into the skin via cracks or cuts in the skin. The area near your nails often has cracks or fissures. Since the virus can spread, you might find more warts popping up.
The good news is that warts usually go away on their own. However if you can’t wait that long, you can see your doctor who will probably freeze them off. It’s important to get the virus out from all the skin cells either by removing the cells or building up your immune system to fight the virus.
