You need to see a podiatrist. It appears to be a viral infection, similar to a wart. They generally (but not always) remain localized. A biopsy will be definitive. There are several treatment options.
Thank you, is it dangerous? I won't be able to see a podiatrist because I'm in a province. We don't have any podiatrist here.
They will do a biopsy. Some of these "warts" are very contagious. Others are not. You don't want to infect others in your family. When they bleed they spread infective cells. Try a moist crushed aspirin poultice. Some of these warts are very sensitive to aspirin. Probably not dangerous, but you don't want to touch it and then touch your eye. Send an image to a dermatologist.
