it's impossible to say what this might be without performing a physical examination unfortunately. there are many structures such as lymph nodes and salivary glands in the area you mention. these could become swollen and painful or it could be something else entirely. if this swelling doesn't clear up within a few days (or if you start to run a fever) it would be worth getting this checked out by a doctor. any time there is swelling on one side of the body but not the other you can't go wrong getting it checked. that said just because you're experiencing unilateral swelling doesn't mean it's anything serious. lymph nodes for example often become enlarged in one small area on a temporary basis and then return to normal size. i hope this helps! i think it is a swollen gland. i get them sometimes as well.
