How long will a swollen upper lip due to allergies last?
My upper lip started swelling last night for no apparent reason. I already took 3 antihistamines through the course of the time from last night to right now (3 tables spread throughout about 18 hours) but the swelling won't go away. I've also applied an ice pack to it,and still no progress.
How long should an upper lip swelling due to allergies last? My upper lip usually swells when I cry but it usually goes away after a few hours or so. It never lasts this long.
