Hi, I had a spot or two of itchy rash on my left breast two weeks ago and before that I also have an itchy spot on my right buttocks that felt like a mosquito bite. Then as days went on the rash spreader through my while body. Now most of them stopped itchy just a but of tingly feeling. But many rash spots turned into pale pink/brown tanned color with dry perky skin around it. The brown marks appear mostly on the sides of my breast, my waist, and my abdomen. Any idea what I had/have? Should I seek medical help?
