So I had a cold last week and my sinuses were very stuffed up and full. Spent a lot of time trying to blow my nose out, but you know how that goes. Ever since though, on the left side on my upper jaw, I feel some pain above one or two of my molars (the ones immediately behind the canine). But the pain is really different. It's not like a toothache. If I run or do pushups or something, I feel a slight ache that pretty much goes away as soon as I stop. It doesn't hurt to chew, or touch the teeth, I have no swelling in my gums or anything, it doesn't hurt to drink cold water or anything else you'd associate with a tooth disease.. I've heard online that after a nasty sinus blockage you can hurt the sinus lining and cause what feels like tooth pain (just because of how close it is), but dental care is very expensive here and I want to make sure it's not periodontitis or anything crazy like that. Has anyone else had a feeling like that in their teeth?
