Recurring rash that starts on neck then moves down torso and when really bad goes to all the way down to my thighs, I though it was from sinus drainage because that s when it normally occurs when my sinus act up, but it s going on now and only problems I ve had is a slight earache, I took an antibiotic last night and symptoms started today, which is the best way to identify what s really going on. I m 41 white male type 1 diabetic, in good shape. Use a insulin pump. The rash thing has happened for the last 10 years normally 2 times a year. Steroid shot normally takes care of it, but no one has really gave me a diagnostic
