Has anyone out there experienced noise sensitivity while speaking? This started a few weeks ago and has stubbornly refused to go away. Whenever I speak for more than a minute or two, I get this horrible feeling in my head - almost like pressure with a little nausea thrown in. It gets worse throughout the day, as I get more tired. Everyday noise bothers me as well, of course, but the noise canceling headphone do help that. It is just that I find it difficult to actually speak at length. I would like to know if other people have experienced this or am I just going crazy?!! Thanks everyone.
