Mark appeared on shin overnight (photo included)

This appeared overnight on my my shin, no idea what it is or where it came from. I haven't injured my leg recently and it doesn't hurt, feel hot or cold to the touch and is not raised. It doesn't feel like a bruise either at all.

I have been diagnosed with IBS and had a blood test a couple of months a go (CBC, Liver, Kidney, ESR) which was normal. I have been unusually constipated and bloated for the last month now but no idea what this rash is.

It's prob nothing to worry about, maybe slept on it wrong, bumped it somewhere without knowing, ect...

Could be erythema nodosum. But that usually (for me anyway) comes with itching. Could be a bug bite, or more likely could be nothing. Wait a few days and monitor it.

Thank you for the replies. I also have these tiny red pin size dots on either side of my shoulder, no idea what they are either! Falling apart at the moment

Piers,

Do you legs ache? Are they swollen? If so, it could be a physical manifestation of Crohn's. I had several strawberry collored spots on my calves and thighs before I was diagnosed. It was originally diagnosed as vascullitis. Once on prednisone, however, the spots never reappeared. Watch it and definitely discuss it with your doctor.

Hi Switalski, my legs don't really ache and there is only a little bit of pain just next to the shin bone but not on it. I've drawn a mark around it to see if it changes at all. Thanks for the advice

I can't seem to work out if the type of mark which can appear with Crohn's is mean't to be raised or not, this is as flat as a pancake. I did do the glass test on it to see if it faded when pushed - it doesn't.

looks like a bug bite to me but i could be wrong.

Hi Maria, that's what I thought at first but it's not itchy, raised or hot and there are no marks on it at all that I could find. It seems like it's a bit of skin which has changed colour for no reason that I can see.

It looks similar to how my Erythema Nodosum began. I had small bumps I thought were bites then they became hard and painful and looked like raised bruises.

Keep an eye on it. I had something just like that 4 weeks ago. Now it looks like the picture below from today. I kind of ignored it for about two weeks. I thought it was an ingrown hair or bug bite.

Today they did some punch biopsies. They think it is panniculitis, which they think could be a result of a crohns flare, cimzia injection, or my current uti and kidney stone issues.

But it started as a small red bump.
