I keep reading in medical papers that for tinnitus 'a thorough head, ear and neck examination should be carried out'. I didn't get neck examined. Did you? Also, why don't all doctors check for objective tinnitus with a stethoscope? I am starting to find reasons why the blood pressure, carotid etc has something to do with the T, for example when I exercises, the T becomes louder, even when I stop moving, then subsides after about 20 minutes. Today I found out that when I hear loud T and I lower the chin, the T drops noticeably. I also have read in this article http://www.washingtonpost.com/wp-dyn/content/article/2009/07/06/AR2009070602919.html about how someone had a carotid problem. There's written that one can tear the carotid with OVEREXTENDING the neck. My trouble started after a visit with the dentist ( I didn't see a dentist for years prior), and I remember I was in a very difficult position with my head unnaturally turned back for about 45 minutes. What should I do? How do I rule out objective tinnitus? any advice?
