Wow hang in there! Did they give you any painkillers? I have found they usually say take advil (which did nothing for me but maybe will help you). Throbbing pain is usually infection you should feel better if you are going to in 2-3 days on antibiotics. Though they say bacteria die off can cause a bit of flare up to. They give you a ten day course? Take the whole course of antibiotics. I sure hope you feel better soon. Oh couple questions is this pain constant? Does it occur only with pressure? In only one spot or several? Seems suspicious it happened after the root canal procedure.

I am not a doctor or a dentist just familiar with pain. So anything I say is just out if empathy don't listen to it if you don't want to.
