I ate out Monday night and thought I had some mosquito bites. I do have a couple, but I m covered with little red bumps, started as one or two on my feet, now on my toes, ankles, bottom of feet and keep getting new ones. They itch so badly that I was up about an hour last night. I bought extra strength Benadryl cream at lunch and just had to put on a second time. I honestly could scratch to the bone. What is it?
