I was exposed on August 12th and I'm still fighting it. My symptoms started the next week. I tried everything I could find over the counter and I kept getting worse. I went to the doctor and was put on Prednisone on the 21st. I still got worse and had a Kenelog shot on the 24th. I was no better and was put on a longer/stronger course of Prednisone on the 25th through Sept 4th. Symptoms were resolved to a very mild rash between Sept 2nd until Sept 10th. Was treating myself with Hydrocortisone and Betamethazone until Sept 16 when it became obvious I was again losing the battle, all of my old patches had re-erupted. I started back on Prednisone on Sept 16th. I'm getting better (again), but for me it's been 5 weeks of itching so far. It never has fully gone away yet and when I try to workout I get a rash wherever I sweat. I'm really interested in the responses you get to this thread because my doctor is baffled, he thought I should have been better in just 2 weeks. I'm afraid I'm going to have scars all over my legs from this.
