I have a total of 7 red bumps on my arms and legs. 1 on my left arm, 4 on my right arm and 2 on my right leg. I thought they were insect or bug bite but they didn't go away. Its been a month since I had the first bump. Now I have 7. They are very itchy. When I scratch them there's this dry skin I have to peel off. I'm a bit worried because they increase in number and doesn't look like its healing. Each bump grows bigger in time because when I scratch it, it becomes a wound then it heals and I scratch it again because its too itchy I cant help. Pls help me what is this?
