About once every two weeks half of my upper lip will swell and have a tingling sensation. Changes from one side to the next with no regularity. It looks like I got a moderate punch in the mouth and is noticeable but not horribly so. The tingling comes and goes with the swelling. No other symptoms occur. I can clarify that the swelling and tingling does not ever cross the mid point no matter which side it's happening on and 90% of the time it's the upper lip.
It last for two hours on average and goes away as mysteriously as it arrives. It first began about a year ago and seems to happen during the last half of the daytime hours.
I'm 56 and in good health. I see my doctor for medical checkups and am 5' 8" and 177 pounds. My blood pressure has always been good and on the low side. I play golf regularly, work hard in the IT field, and have been exercising moderately hard for the past 9 months.
The problem doesn't appear to be more than a nuisance but the tingling makes me wonder why it would do that. As I indicated it's not horribly swollen, just moderately.
