I woke up this morning with a bumpy red rash that was extremely itchy all over my body. I took benedryl and within two hours it came back but ten times worse, I also got very very cold the second time and my hands and feet are completely swollen, I can't even put pressure on my feet because my feet hurt so bad. My hands are very stiff as well. My ears are also very itchy. I haven't changed anything in my schedule, diet, or any body soaps/ perfumes or detergent and I haven't been stung by a hornet nothing .
