Odd rash

[SLT5810]

About a week and a half ago I started itching, a rash has appeared on my arm, lower stomach, and butt. It seems to be spreading, the itching in driving me insane. I've got an appointment to go see a dermatologist, but it's not until later on in the week. Any ideas on what it may be caused from?

Hello,
It can be due to allergic reaction, scabies or heat rash( less likely). If it is painful then herpes is an important possibility. Scabies is a contagious  skin infection caused by a parasite – the mite, which burrows under the host’s skin and causes intense allergic itching. It is transmitted from objects or beddings, but more with direct skin- to – skin contact.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

There's a picture of the rash.
I've been pulling up all kinds of pictures of different rashes but none seem to match up.
