question: Recently, (today) I am having a sharp pain in Right under the left side of my jaw that is unusual. Though I can not see it, I can feel minor swelling the submandibular gland, and my saliva on that side of my mouth has increased. What level of concern should I have about this? Changes to my habits recently are the following: I have started exercising more intensely, but I have not been drinking as much water as I could. Also, I have begun working in a resturant handling dirty plates and such. Lastly, I have had two sexual partners in the past month. I do not the sexual histories of either of them, and in one instance the condom broke during an encounter. Thank you for your time.
