Diagnosis: The best advice i can give you is to see an ENT specialist and have an appropriate diagnosis. The ENT specialist can document three things. 1.) a specific and proper diagnosis, 2.) perhaps a cat scan to document that diagnosis and 3.) appropriate medical or surgical treatment based on the diagnosis. Remember, always, diagnosis precedes treatment.
