hi I have this recurring pain in my jaw.  The first time I was sick for a month and bed ridden, couldnt eat cause I couldnt hold anything down.  Since then the right side of my jaw from time to time feels swollen and achy.  At the moment it is bit more severe as I get soars in my mouth also, just like the first time.
Thanks for your query. I have gone through your query. The pain and swelling can be because of the abscess formation secondary to tooth or gum infection. Nothing to BR panic, consult an oral physician and get it evaluated. Meanwhile, you can take a course of antibiotics like amoxicillin and metronidazole(if you are not allergic). If it is tooth or gum infection, it can be treated with root canal treatment or scaling respectively. Regarding the soreness or ulcers, it can be stress induced leading to authors ulcers, you can take topical anesthetics like lidocaine gel. I hope my answer will help you. Take care.
