Wow I am glad he finally got in with the right doctor. I've had my share of throat & nose problems and I do believe there is a tendency for less educated doctors to not really take the necessary steps to diagnose a problem and just use trial and error to fix the issue. Probably works most of the time. I've had nasal congestion problems all my life, been to at least one or two specialists when I was a kid and never had anyone even put nasal scope up my nose until I was 25. Finally got in touch with a good ENT when I was in the hospital with throat swelling problems.
