Hi,
About a month ago, I (36 y.o man) took one paracetamol capsule before bed, and when I woke up, I suddenly felt that the inner part above my upper lip (the mustache area, but on one side) started to swell. After 3-4 hours, it almost completely gone. I should mention that when I took that paracetamol capsule, I was trying to be funny in front of my girlfriend and placed it between my upper lip and gums, as if I had one big tooth.
Two weeks ago, I took paracetamol again, around 6 AM, when I woke up, and went back to sleep for another two hours, and the same thing happened exactly when I woke up (as if the reaction was “waiting” for me to wake up) - swelling above the lip, on the inner part, on one side. No other side effects. After a few hours, it went away.
Last week, I took Omeprazole for heartburn in the evening. Immediately after that, the exact same area swelled in the same way, only this time a bit more significantly. It took several more hours for the swelling to go down (it completely subsided by the next day afternoon).
Have I developed an allergy to one of the inactive ingredients in the medications? What could it be? Besides going for allergy tests (I have an appointment), have you heard of a similar phenomenon?
Thank you
