hey,
I have just recently gotten back into cycling and an odd thing has happened since i have. When ever I ride hard and for a period of time (1 hour or so) once I have stoped my eustachian tubes (mainly left one) get stuck open which makes my breathing sound extremly loud and is rather annoying. It stays this way for about... 10 to 20 minutes, this happens to me sometimes when i play soccer for a while too but it has only been doing this for like 3 months.
Do any of you suffer from this random thing?
Edit: I just did some research and it sounds like a super mild version of Patulous Eustachian Tube aka pEt. pET is when it's open for most of the day though and mine is open only after hard excersize for a short period of time.
