Behind my right lower molar is swollen and very painful. My throat, tongue, and left ear also hurt not sure if this is related. I use mouth wash daily and never have had any problems. But today it burned very intensely and almost foamed. Whats going on? A little background on me. Female, 22, I have TMJ, and grind my teeth when I sleep. Ive only had one cavity and had my wisdom teeth pulled two years ago I have PTSD, Major Anxiety and Depression. Im a victim in a case and trial starts in 6days. HELP
