This place does dental and medical. I'm just going to assume it's for dental. Warm salt water to gargle. No smoking No spicy foods. Plenty of rest. (Most important!) If condition worsens, definitely go to an emergency room.
You should have received a paper with detailed instructions after your visit. If you are having trouble afterwards be sure to contact them. If you feel like its a medical emergency which it can be, go to the hospital.
I'm not a hundred percent sure but it's probably going to be like Tylenol
