My kneck started swelling at around 8pm last night, about 1 hr after I ate. I couldn't sleep at all. I couldn't breathe very well. I noticed aroud 5am this morning that my neck swelling was going away, but then my face stared to swell. It is swollen to the point now that it is stretching my lips and face and causing pain. Anyone have a clue. I' ve been searching the internet for hours. Iam a 48 yr old male with high blood pressure. It is 176 over 104 right now. Thanks
