### input:
This morning I had a carton of tart yogurt. As I ate it, I felt the tingly feeling you usually get in the corners of the jaw when eating something tart/sour. Only it was ridiculously strong on one side, almost painful. My jaw on that one side (left) felt tingly and almost numb. When I looked in the mirror a few minutes later there was a large lump there, right in front of my left ear. It had not been there before. Since it s Sunday, I decided to wait a bit before rushing to urgent care. It s been six hours, the swelling has gone down but is still there a little when I touch or look closely. It s also tender there and below the jaw. Should I go to urgent care today? Or wait until morning? It s now 3:30pm. I m afraid of an infection or bells palsy or something scary. I should mention I went to the dentist for a cleaning 6 days ago and recently switched to a powerful toothpaste (which seems to have burned my tongue, affecting my taste a little ). Please advise.

### output:

You can wait till morning to report. The swelling needs an appropriate examination since you already visited your dentist just a week back this would not be due to an urgent dental complain as if so you would have been treated or informed of the same. Of the swelling in the external it appears to be due to some little blockage in one of your salivary glands or a rare thing can be allergy due to the toothpaste that you have been using. Since your toothpaste has already caused you problems I suggest you to revert to your original paste also avoid any sour and spicy food, eat plain salted things till you get your problem diagnosed.
