Hi. I'm John. I'm 62. I've had tinnitus for a long time - maybe 20 years now but until recently it has been at a very low level. Most of the time I didn't notice and I could go weeks at a time and never think about it. Then earlier his year I started a course of Levothyroxine for an underactive thyroid. I had a couple of months on 25mg a day, then 50mg a day, then up to 100mg. About a week after I started on 100mg I noticed my tinnitus had got a lot worse and I told this to my doctor and we agreed I should go back down to 50mg. Over the course of the next few days it got steadily worse and I decided to stop the medication altogether. To my horror it continued to get worse for a few more days and it reached a point where I was in total despair and thinking very dark thoughts. This was August 15th this year. I was convinced it was the medication that had caused it but my doctor disagreed saying it was just coincidence and that the Levothyroxine was simply replacing what my body should be producing naturally. I can't find Levothyroxine on any list of ototoxic drugs so don't really know now what caused it. I've not been exposed to any loud noises or had any ear infections or anything like that so I'm still thinking it was probably my medication. The first month after that was hell. No sleep, scared, off my food. Just worried sick and feeling very sorry for myself. Slowly I have found that I am starting to cope a little better. Not sure if it's down to habituation or the Tinnitus has reduced in volume - maybe a little of both. I've been playing around with DIY sound therapies so glad to have found this forum as there's lots of good info on this topic here.
