I've seen a couple of ENTs for the same problem, but this time I had a specific thing I think is causing it, so I went in and asked to be tested for that. About a 45 minute wait, they were busy and that seemed normal for wait times at any doctor. The nurse immediately set me up with the first few tests, the doctor talked to me about the second round and I was scheduled for those tests within a couple of weeks. They were nice and helpful in the office.
