My husband scared me a bit last night. He started complaining of itching and was covered in welts within a couple hours. We tossed around the idea of going to the ER but in the end just tried Benadryl. Fortunately that did the trick and he's only got a few welts this morning. He didn't have any new foods and we haven't changed soaps or detergents or anything lately, so we are mystified.
