I have two swollen/puffy "lumps" under my lower lip near each corner. This is new - I'm wondering what's causing it. (photo)

If I touch the spots, I don't feel any masses. There hasn't been any trauma to the area. I do have bruxism, perhaps that's a factor? I'm already noticing changes to the symmetry and bulkiness of my jaw (and my dentist recently prescribed a nightguard). Any advice would be greatly appreciated!
