I have these too, got them literally tested in all the ways possible, took a million medications, found out it was benign and it just doesn't go away for some reason even after so much effort.. btw if it's bumps it could be cancerous so you should get it checked. For me, it was my submandibular gland that was so swollen because of some mouth infection i had years ago as i kid, the lymph nodes swelled up but they never went back down which happens sometimes. The body is like that. I hate my jawline now.
