Hi two weeks ago I was outside, I was in out all through the day I wore my sunscreen when I applied it always burns a little but went on as normal that evening about dusk, there were flying insects . I didn t pay much attention because they usually don t like me, but later that evening I wash off my sunscreen from my arms to put on my moisture cream and I found some what appeared to be bites or welps . I applied alcohol and a cortisone cream. They still are there but they are no longer welped ,but some are flat and appears to have been opend, I now use witch hazel and benedryl cream I also have been taking benedryl by mouth for about a week and 1/2. Each time I use my sunscreen they get worse.
