Your swelling might very well be muscle related and not infection. However, that is what I thought for five years. My swelling fluctuated. My body would get it under control, then it would flare up again. I took lots of antiobiotics, but antibiotics won't cure an infected tooth. The only thing that will cure an infected tooth is a root canal or pulling the tooth. Hope you don't have a tooth infection. I wouldn't rule out anything though.
