Since two days I am feeling whole body itching and it was mild at beginning from below the neck then extended to stomach and now feel itchy developed reddishness and hives ,it go away after 15-20 minutes but again starts at another part of body or two or more parts at a same time, I never faced this before. Kindly suggest me what to do, it's very uncomfortable for me even to sleep. It itches like anything and I scratch the body like monkeys. The body part gets rashes when I itch. At first I thought there might be mosquitoes somewhere in house, but when it worsened I realized that this is not mosquitoes but it's an itching.
