I am really scared...

After I had my son I developed a tooth ache it was where my wisdom teeth are. The pain went away after a day but when I woke up I couldn’t open my mouth more than an inch and it is painful. It has been 3 days and I still can’t open my mouth more than an inch without it being in pain, I avoided going to the dentist because where I live they so bad I did make an appointment but it was during a time my son got out of school so I couldn’t go; so I took Tylenol and Motrin, massage the area, put a heating pack on my jaw to get it to open but nothing is helping. I can feel it in my throat when I swallow and sometimes it hurts. I look it up and of course it tells me I’m gonna die and now I’m scared, I can’t see a dentist till possibly Monday and idk what to do!!!
