Hi!  I have been having this pain behind my right ear.  It started two weeks ago and I thought I just slept on it incorrectly.  The pain comes in lusating waves from the base of my neck behind my right ear.  The right side of my head has this tingle sensation.  I had Bells Palsy back in 2007 on my the right fron of my face.  Recently had a crown and my DDS found an infection and sent me to an endodontist who did a root canal a week ago.  Both the DDS and endodontist dont think the pain I am still having is from the tooth onfection.  Any thoughts?
Hello, Thanks for posting your query in Chat Doctor forum. The pain can be either due to re-infection of root canal treated tooth or due to improper placement of crown. Please do visit a dentist and get a thorough clinical as well as radiological evaluation done. Tooth has to be reject treated or crown has to be replaced, depending on the causative factor. If symptoms persists, please do visit a neurologist as well as an ENT specialist. Take care.
