ve googled
and see that some potential causes are cellulitis, hypothyroidism,
tooth abscess, allergies, trauma, infections, inflammation, I think lupus?, and cancer. I have had some recent dental issues (infection, teeth pulled, roots left too long after a tooth fell out). Has anyone had this? So weird. I mean, I guess I should assume it's from the dental stuff, but I just had another panoramic xray, and the dentist said everything was fine.
