I totally agree with everyone that says stress is a contributing factor.. I believe it was strongly linked whenever mine flared up.
Not long ago, I used to work in a job and in my line of work (marketing) there was a lot of pressure to deliver to clients.
I used to be one of those workaholics who was usually first in the office and last to go home as I wanted to go the extra mile in my job - what I didnt realise was that I was kind of my own worst enemy because -
1. I never got enough sleep as I worked quite late
2. The job was highly pressurised, with a lot of deadlines to deliver on
3. I drank a lot of coffee (stimulant)
4. Did not really relax even on weekends, as to cope with the demands of the job I would sometimes work then too.
Ultimately it took a few times for me to notice that this contributed to "spikes" in my Tinnitus so to speak. I used to have it quite intrusive - the last time it happened, I had planned to go away with the Mrs for a few days but prior to that, the week was mega stressful. I let it kind of get to me and it spoiled my weekend as all I could think about was my raging T.
Eventually, with time, the spike wore off, but I continued having it intermittently.
To the present, I left my job to take a few weeks out and I've been relaxing a lot more. I'm happy to say I'm not feeling any kind of stress I used to in my job and guess what, my T has really really improved. So believe me what these people are saying - If you take care of yourself, dont stress out over it - sleep lots , I believe it really is an effective way of minimising / controlling your T a little more
.
I hope this helps
