Experiencing  nasal drainage, pressure in right sinus , under eye and allergies
Patient: I had a root canal done today and he said that he hit the lingual (sp) nerve that caused a sharp pain. I started sneezing soon after that. Now I have severe nasal drainage, pressure in my right sinus and pressure under my right eye. I have seasonal allergies and this almost feels the same but just on that right side. I am 29 years old, 5' 2". I have had many dental injections and this has never happened before. Doctor: Hello, Thank you for consulting with HCM.It looks that while performing root canal treatment on the tooth the dentist has punctured the wall of maxillary sinus and now it is causing  drainage.Better you visit an oral surgeon and get a complete examination done. and if necessary get the tooth removed.Hope it will help you.
