So a couple of days ago around noon I noticed I had red dots on my inner thighs that were also itchy. The itching and spreading of dots got better and eventually subsided. The other day I noticed more red dots and on a larger portion of my thigh. Within the next 24 hours the rash was super itchy and I had tons of dots and red areas all over my body but especially on my thighs. It seems the more I itch the more it spreads. The doctor i went to said it was an allergic reaction but I refuse to believe that because I haven't tried or done anything different in my life. Do you think it's pityriasis rosea?
