Post root-canal by 10 days, still in a ton of pain with deep jaw ache, metal - chemical taste, more pain after eating. Have crown scheduled for 2 days from now but don't know if I should proceed with remaining problems from root canal. This root canal has taken place over the course of 8 weeks in 4 sessions due to calcification build up they injected a medicine and made me wait to finish it just a week ago Wed. Pain management is non-existent. Ortho won't prescribe any more pain meds. I am on my 2nd course of steriods and of antibiotics. This is causing me severe headaches, pain radiates into the ear and forehead, some throat issues, inability to sleep, etc.. What is the best course of action - go through with a crown, get it pulled or go back to ortho to get another assessment of the root canal job? I am sick of this nonsense.
