i have a bug bite on the back of my arm. originally i thought it was a mosquito bite, but it has bothered me for two weeks now. It had a scab on it, that was scrubbed off in the shower, and now the area is red, small blisters surrounding the original bite area, and itchy more than usual. i have applied topical anti-itch cream off and on for the last week, and today, due to it s bothersome nature, i have applied tea tree oil 2x and peroxide 1x.
