I have been experiencing reoccurring bites in my upper body, mostly arms, neck and face for the past 6 weeks. I initially thought i was having an allergic reaction to a bite, possible mosquito or spider - but after a week and more appeared I went to the Dr, got a shot and a 6 day pack of prednisone, with no relief. Then went to the Dermatologist - did another round of prednisone, which I finished 3 days ago and I am still breaking out. I have cleaned, replaced all the lines, don't use any fragrances anyway because of my sensitive skin and allergies - I just want to stop itching and the reoccurrence of these bites. HELP
