I get those before my period or if I drink alot of caffeine. What I have been told they are your glands that are swelling. I lay off of the caffeine for for a few days and drink lots of water
You have lymph nodes there. I had a friend who had one swell up on her and it turned out to be an infection. I would not waste my time on wondering, please get it check out.
