NeuroTalk Support Groups - Strange feeling on my left cheek.

hi! i'm new here, but i was Googling about the problem i may have.

i've been looking on some topics on this forum, that seem to describe my problem, here are the links:

Since a few days ago, i've been having some kind of discomfort on my left cheek, sometimes it come, sometimes it go, but it's most noticeable when i go to bed, when my left cheek is on my pillow, sometimes it feel unconfortable. Since the last few days, i've woke up a few times during my sleep, but i wonder if this is related to my problem.

About a month and some days ago, i had 2 cavities fixed (1 on each tooth) on this left side of my jaw, and i remember the dentist saying 1 cavity on 1 tooth is near the root. After the appointment, i asked him and he said it look great.

But i didn't had this problem right away, 2 weeks ago i had some small pains in my teeth that seem to fade away after a short time. But as i said, this kind of problem seem like it appeared about 2 days ago. It feel like a discomfort, or swollen, my mother checked my face and it doesn't look swollen, though it feel like something's not right. I can still feel when i scratch there. And about the teeth pain, i still have my wisdom teeth, the dentist did told me to come back later (or "eventually" as he told me), and also to come back to repair 2 other teeth on my right side.

I must say that i'm an anxious and stressed person...in fact, i started feeling very anxious at the same time i started having those small pains, i've been asking a lot of peoples, on forum, some friends, and my mother about this. My mother said it's alright and you're focusing way too much on this.

i've been thinking about taking another appointment so the dentist can have a look at what might cause the problem. I don't know what he/she will say about this though.

Previously, in August, i had 2 teeth removed on my right side of my jaw (2 molars). The dentist (who did the extraction and repairs) also numbed me by using, i think, 4 shots of...i don't know which stuff exactly, i remember asking the receptionist but i forgot.

Since this is happening, i bought myself an extra-soft bristled quality toothbrush (Colgate), floss for sensitive gums, and a bottle of Listerine, the "Total Care Zero" one that doesn't contain alcohol.

Thank you very much for reading my whole post and for helping me, it's greatly appreciated!
