Angioneurotic odema. An allergic process. Do consult your Doc.
To help, I took liquid antihistamine, with a shower. but i also had itching. About 29 years ago. I woke up with just my upper lip, very swollen, I looked like a duck. luckily, even though i looked funny, i tried to see the humor. My face made me laugh. I had to go to work, and I just dealt with it. In addition to that i slowly lost my voice that day as well. But by the next day it was gone. The true loss of my voice, lasted 3 to 5 days. the first days. i would go to talk, and No sound came out. That worried me, but not talking i didn't have to answear phones. 3rd day i made a whisper, and slowly it got better. Then when i had the duck face it was nerves that brought both symptoms. Today's i was vacuming. moving things around on floor. Remember the benadrill will hit you very soon after taking it and make you Very Very sleepy. So don;t plan on doing anything but sleep. Can be deadly if driving. Good luck. I hope you feel better soon!
