I've been looking into this symptom that might be contributing to my (and maybe others) T. I've had T since early 2012 but have often forgot about it until it went off in April this year (2014) to an alarming level in both ears. I had an upper respiratory issue and I'm very allergic to certain tree pollens which both had a lot to do with my T this year. In April I didn't make the connection with T, allergies and pollen but good news is it has reduced since the tree pollen is not as high now. Early on, the ENT and Allergist prescribed me Prednisone and Antibiotics. When I finished my meds, I noticed my tongue had an excessively white coating on it. I discovered it was a side effect from taking those meds that is called Candida or Thrush Overgrowth in my mouth. WTH!? My GP gave me a Nystatin Oral mouth wash but that did very little. I've been reading up on it and it's basically a yeast infection but you can't get rid of it, you can only (hopefully) balance it out with good bacteria to get it under control and changes in diet. Every one has it in their intestines but when your immune system gets weak it can spread into other areas of the body such as on the tongue. One individual in a Candida support forum claimed to be an authority and seemed to be knowledgable on the subject and used to have it so bad, including T, he tried everything but only Nystatin enemas (plural) worked. It worked and it stopped his ears from ringing! He said Candida produces many toxins and once it gets out of control it causes the body to react and have many multiple symptoms. He explained that Candida is not in the ears but when the higher levels of toxins produced from the overgrowth in the intestines gets into the blood stream, it ultimately gets into the brain and causes ringing! In the Candida forums, there are other people who have claimed that when their Candida was at it's worse it made their ears ring. Some people have it real bad, I do not but to me it's noticeable. I use a tongue scrapper but the back of my tongue still gets this white coating in only a couple of days so apparently I'm still dealing with this issue. Check your tongue. If your knowledgeable on this subject or have similar symptoms please comment.
