Russ55:Doctors are expensive. Why pay for one when you can ask random strangers on the internet? Well, I'm not a doctor, but I pretend to be one when I am picking up on high school girls. It could be an allergy of some kind, or a reaction to something else you've put in your mouth...or something someone else put in your mouth while you were sleeping.
In all seriousness, look at everything you've been eating or drinking. Look for new stuff. It could be a lot of different things. Do some analysis, and try to eliminate obvious possibilities. If you're sure it's the cigars, look at the specific cigars you've been smoking. It's kind of a big open question that's going to take some effort on your part to solve before you can really narrow it down.
Crisius:I had this happen just last night while trying a "Sol Cubano Cuban Cabinet". It really irritated my mouth, I loved the flavor but it caused my mouth and throat to swell. It was almost like an allergic reaction, which I'm used to getting. I'm mildly allergic to eggs so in super eggy foods my mouth and throat swell a bit. And peanuts can literally kill me. So I know what one feels like. Which is irritating in another way because I really liked the taste of that cigar.
