Rash Diagnosis

Something weird happened today. I woke up and I have this rash on my right arm and hand. There is a blob on top of my hand (directly under my fingers) and another of the same size of about two inches on my wrist. The eruptions have a distinct end point does not disappear into my skin. The rest of my body is beautiful and as I said they just jumped overnight.

The symptoms are basically it just feels hot as I am now back in my right hand and wrist over a stove. Otherwise, I'm finding. I can not think of anything that might have caused, but anyone who can perhaps point me in the right direction would be greatly appreciated.

TIA

Doctor!
