Hello

I have discovered that one of my buttcheeks has this weird, peasized "thingy" on it. It looks a bit like a combination of a rash, a birthmark and an old pea under my skin. It also feels weird... it's like a hard lump.

Can anyone tell me if I need to be worried? It's been there for a couple of months I think, slowly evolving from just a birthmark-lookalike to this thing?

Answers greatly appreciated

I would get this looked at. It could just be a mole growing in or skin cancer. There isn't much we can tell you about it from what you've described.

Have it looked at.

You will need to have it checked. It could be anything from a cyst, ingrown hair, to cancer. We can't diagnose online.

See your doctor.
