I went to an urgent care center this morning. Symptoms are what I would describe as a mini sinus infection on the lower right side of my sinus cavity, inflammation which causes enough swelling in there to be pushing my upper right teeth slightly out of place. The result is pain and a sensitivity to cold in the upper right portion of my mouth. The funny thing is there is no yellow or green mucus that you would expect with a sinus infection, anything that comes out is clear. Breathing is unobstructed. Back in December I had a bad sinus infection. The doctors opinion was that it was a residual effect of the viral infection aggravating the nerve in that area. I forget the term he used of it, but does that make sense?
