My daughter has a pea sized bump on her thumb. The bump looks like a blister but is hard as a rock and has two small black dots at the tip. It has been there for 3 days but I don t recall her getting injured in any way. I have no clue what it is. It doesn t bother her but it s driving me crazy.
Hi. Thanks for your query. The hard pea sized lump on the thumb-with 2 small black dots is suggestive of a viral wart. It can easily be treated by applying the solutions available for warts. You have to be careful to save the skin around the wart. If you are not confident about careful application have a consultation with a Dermatologist. The part being a thumb-you have to be really careful.
