Hello! The medical history is not detailed.
According to your description, it is estimated that it is a nail mole, which is generally benign. It is indeed possible to get sick, but the probability is low. Surgery is the first choice for treatment, and it is recommended to consult a plastic surgeon in our hospital, such as Associate Professor Wu. I wish you a speedy recovery!
