Hello,
I'm 20 and about two weeks ago I got some weird itchy rash. Recently it's becoming unstoppable. I have never had any kinds of memorable rashes except chicken pox. I'm allergic to dust so I very rarely and for a very short time have itchy skin, but just in contact of a lot of dust.
I am using Triamcionolone Acetonide and helps a bit - the rash is slowly fading away, but it just keeps appearing too fast and now it's pretty bad.

There is no possibility for me to go to see a dermatologist in next 3 days and I'm panicking now.
The rash is basically everywhere below my chin, except palms and the part of foot I'm standing on (sorry, not a native English speaker).
Also, this rash often goes in line so it might be connected with blood flow. Now I'm worried because it may indicate some very bad infection? Do you have any idea what this could be?
Thank you for help!
This picture is from yesterday. Now it's a bit worse on this arm and the other arm is becoming a lot like this one. My back too.
