I have a rash that started off as hives, but have turned into dark/purple spots/stripes all over. One doctor said it was pytriasis Rosea, but another disagreed due to the discoloration and clustering of the spots. Itching has subsided, but rash is spreading. My inner arms/torso look like zebra or tiger spots, my inner-thigh spots are more circular with purple/red tones. & they re also clustered. Don t know what this is! Help!
