Ok, so I have a horrible rash all over my legs and arms. It just covers my whole upper arms all the way around, it itches SO much, and it hurts when anything touches it. I started getting it on my arms on Sunday, and now it is all over and getting worse. Now is this just die off, or could it be a bad reaction to something I am taking. I am thinking die off, but can people let me know if they ever had a rash like this. It is clear and very bumpy but when you itch it it gets very angry.
