@LadyDi here is how my life went with T:
I had a sinus infection about 2-3 weeks before I went swimming and got water stuck in my ear overnight. This was in June. The day after that was when my affected ear felt a little painful and I hear cracking noises in my ear, which is a supposed sign of ETD. I got used to ETD and had it for 3 months before T started for me. This means that I am not entirely sure if my T is due to ETD, although the ENT said so. My T has gotten much better now, my ETD has been the same all this time. I've not had a bad cold or a sinus infection since then, but I have a runny nose all the time, so I don't know if that means something.
Based on my background, do you think flying is safe for me? The valsalva method works for me, especially in the morning, when I suddenly can hear much more clearly after doing it.
There are times when it doesn't help much.
