What causes an arm rash?

Trying to find out what this is on my arm? I have a rash.

Hard to say. Differential diagnosis includes and area that you are picking at or even a squamous cell cancer. As far as a rash, all I see is one blurry lesion. Sorry I can’t be of more help. I’d have that checked by a board certified dermatologist.

Warm regards,
Not sure. But could be spider bites. Definitely looks as if something from outside irritated the skin.

Looks like you have a crusted area on your arm, probably caused by scratching. To find out what is causing the itch, best to visit a local dermatologist.
