Throat Pain When Breathing In

I've been having this pain in my throat that is most prominent when I breathe in. Coughing, swallowing, chewing, speaking, and laughing are not a problem. It starts in the morning when I get up, is constant throughout the day, and eventually begins to subside in the evening and night (around 7pm). This has been a daily thing for about 3 months. Sometimes I feel the pain at the base of my throat, and sometimes I feel it up in my sinuses, behind my nose. It’s hard to isolate the exact place the pain is occurring. I do not have sore throat, runny nose, congestion, swollen glands, fever, or any other flu, cold-, allergy-, or sinus-relate symptoms. I have seen an ENT and she put a scope in my nose and looked through my nasal cavities, but not down my throat. She saw nothing of concern (except a deviated septum, which she was not concerned about). I have had blood work and a CT scan on my sinuses and am waiting for results; but suspect this will reveal nothing. This does not keep me up at night since the symptoms (for the most part) subside by the time I go to bed. I am a 49 year old white male. Do not have HBP or heart disease. I do not smoke. I do drink a couple of beers a night or less. I am not looking for a diagnosis so much as possibilities to ask the ENT doctor on my next visit. Doctors have a tendency to compartmentalize the way they diagnose problems rather than looking for a series possibilities. Any help is greatly appreciated.
