Hi, these pimple sized rashes have been growing all over my body. They first developed on my feet , then they spread to the side of my torso, breasts, and back. Now some are starting to grow behind my knees and under my forearm . They re itchy and it gets more irritating at night when I try to sleep. They seem to get redder as time progress. None of it has go away yet. I have these rashes for 4 days now. I visited my doctor 2 days ago and he said i may be allergic to something I ate and gave me medicine and cream. For the last two days, the rashes just seem to grow redder and more are slowly growing. What are some possibilities for the cause of these rashes?
