Hi there..my name is Jessica.i developed a rash for about 2 wks now..it started off with little red bumps that were very itchy and it started on both of my arms I just figured it was from turning on the heat in our house and I live on the second floor I ve never had this before so I figure I give it a couple weeks and it should go away well now I m getting really worried ..it has spread to my back ,my inner and outside of my thighs,down behind my knees,my stomach and now starting to come out on my face,,oh and in my right ear.its very itchy and scaly..now the red bumps are all cluttering up and kind of looks like the letter C in most places..what can this possibly b?
