so I've had this condition for over a year, havent been able to afford to see a doctor. The itch gets worse in the evenings/nighttime. The area that itches starts at my upper thighs and goes almost all the way up my buttocks. I originally thought it was a really bad heat rash, but it wont go away. I treated myself for pinworms at one point thinking that was what was wrong, but the itch persists. Only recently (to my knowledge) has the discoloration occured. I just wanna know what this could possibly be.
