<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi, i went today at my dentist to do a root canal at 12pm and whiles having the root canal i endured very excruciating pain throughout my whole face, and after it was done my face was swollen, and then 6hrs later, around my whole right eye is very black blue the pain is still very intensive, can you please tell me whats wrong if i should worry or not? thank you  <response>: Hi, I went through your query. It is unusual to have so much pain and swelling after root canal therapy. If your right eye is black and blue- It definitely suggests Sodium hypochlorite extrusion into the bone. Swelling should come down in 4-5 days. If swelling doesnt subside in 4 days u should contact the dentist immediately. For the time being, I suggest - Augmenting 625 mg three times dailyIf you are not allergic to it and Tab enzoflam three times daily. Apply ice packs from outside hope this helps.
