Swelling started 1 day after the root canal. I am taking Amoxicillin, Motrin, and Tylenol. The area of root canal feels good. If body is still swollen tomorrow, I will go to hospital, shelley
Check with your doctor or dentist today, not tomorrow.
It sounds as though you're having an allergic reaction, likely to the Amoxicillin. They are common.
Allergic reactions can be very serious, including fatal.
