Looking for someone with knowledge of skin!

Hi!

This is a long shot: I have a rash literally from head to toe. I assumed it was guttate psoriasis, but it isn’t behaving like that. It’s mostly focused on my vagina and under arms and inner leg. Almost as though irritated by sweat. However it is elsewhere including feet etc. I am on a waiting list to see a derm but it’s half a year... I’ve also been assured by a doctor it isn’t life threatening/ but I was wondering if anyone on here had ANY knowledge of rashes. If so please please comment!

This is the rash near my groin. Elsewhere it is more dispersed in little round dots.

Huge apologies for grossness!
