I have developed a rash. I would liken it to goose bumps. In my web searches, Keratosis Pilaris is the only explanation I can find; however, these bumps appear not only on the upper arms, but also the inside of the forearms, thighs, and calves. You can only see them when the light is down cast upon them and can barely feel anything by touch. They ve been there for a week no with no improvement. I went to the urgent care on Sunday, but the doctor couldn t identify it and said it would probably clear up on its own. I am not as confident as I ve seen no improvement at all.
