For the last year and a half, I have had recurring rashes
. They are typically clusters of itchy bumps that puff into bigger bumps when I itch them, and are sometimes red and sometimes not. I originally got them on my inner thighs, but they appear also behind my knees, on my arms mostly by my elbow joints and armpit areas, and also up my biceps and triceps area. I also get them in the upper chest, and occasionally on the neck.
