Granuloma Annulare. It usually goes away, maybe not totally, yet does reduce in size, color and itchiness within 18 months. I had cortizone injections at the site at my dermatologists. They first thought psoriasis, tested negative. Then Simplex Lichen Chronicus , again negative. Ive significantly reduced in size, color, and itchy and flakiness over a 2 yr period. Its now summer and Ive noticed them to become inflammed but not as severe as initial outbreak.
