Red Mole

[Doodliedo]

I struggle with anxiety so probably overthinking it but a week ago this red mark appeared on my arm , which is painless and not caused by anything obvious. I assume it's a mole it has become a bit crusty on top but just seems to be one colour and has appeared from what seems to be nowhere. Please can anyone reassure me that it looks innocent or am I being reasonable to think that it may need checking out?

From the picture id say it looks more like a healing spot or bite, a patch of excema or impetigo. A mole would be the last thing i'd think for something that's appeared suddenly, and that colour.

Personally I'd whack a bit of sudocrem on it twice daily and keep an eye for a week or so then, if it hadnt gone away or gets worse at any point get it checked out by GP or pharmacist.

Hopefully it'll clear up ASAP.
