It has happened twice to me so far and I'm curious if anyone thinks it is paddle/water related: after paddling and rolling in the Potomac (warm, relatively clean), I get acute pain in the jaw, about a day later (over night). On both days I also drank a lot of cold (from the fridge, no ice) liquids fast, as I was also doing some yard work on a hot day and sweated tons.
I am not sure if I can attribute this to some infection from the river or to the cold. It might even be an irritation of the ear canal when I dry it after a shower with Q-tips: I've noticed mine has narrowed over the years and too much "massaging" it seems to result in a mechanical irritation of the tissue around the canal, not inside, presumably from mechanical pressure and stretching it to get the q-tip far enough inside.
Anyone else with something similar? It is quite annoying as it lasts several days and gives me a problem chewing food as it hurts as I open/close my mouth, but it also is so close to the ear canal that I can't pinpoint if it s a jaw issue or something with the ear or throat...
