I have heard that grief over the loss of love ones can trigger T. It is probably the stress factor which contributes to the onset of T. The wife of the janitor couple of our office told me her onset of T was soon after her mom passed away. So there is some validity to the linkage of grief and T. But she has recovered from her T and she said most of the time she couldn't hear it. It is also reported by some members that their T started after taking some meds, such as just cold medicines. So there is validity to the meds connection. Nevertheless, whatever what cause it, it is best not to fret over such things. Too much focus on T and its causes can cause us to tip-toe around T which in itself can cause stress to build up and therefore louder T ringing.
