Anybody have a clue what this is on my leg?

A few months ago I had something red and U shaped appear on my skin on the back of my hamstring. It has gotten bigger and varies between pink/red/purple. At first I thought it was a bruise so I started using Arnica but it didn’t help. I went to the GP who treated it with an ointment for ringworm (he wasn’t sure if it was that but had no other idea so we tried it) this also didn’t work. I have now been put on a much stronger steroid cream but nothing is happening.

It is slightly raised around the edge, it’s painless and there are no spots or itching but it’s not great to look at and I’m constantly asked if I have been bitten (by a person!) not sure if I can upload a photo here?

Hi, I think the best idea would be to see a dermatologist, they are more knowledgeable than a GP in issues like this.  Another thing it might be is Purpura, here is a link to it.  https://www.healthline.com/health/purpura#outlook  As I said, it would be wise to see a dermatologist to rule out anything that could possibly be serious.
