question: A little less than two weeks ago I woke up and my lip was swollen, it itched a little, was warm, but did not hurt at all, it was actually numb. It ended up swelling up HUGE. I went to the hospital and they said it was probably an allergic reaction, they prescribed me steroids and said to take Benadryl and go see an allergy doctor. Well, about two hours ago my foot started itching and getting warm, it's a little swollen and my skin feels tight so I can't walk normally. It's on the top of my upper right root, under the big down. It's warm too. I remember this same thing happening to my knees about two months ago but I did not think anything of it. I'm kind of a hypochondriac, so everyone told me not to worry about it, "it's probably nothing". But I know my body, and I know when something doesn't seem right. Please help!!!!
