I am 30 years old, born 9 weeks early. I always thought I had poor lung capacity, but I never had it checked out. This may be separate, but I feel like I have had bad blood circulation the past few years; for instance if I am wearing skates or shin guards my ankles, or anything tight on any extremity I feel discomfort as if the blood isn't pumping easily to it.
So my whole life whenever playing sports with hard sprinting/skating after a single shift I feel like I'm dying no matter how good condition I am in. My lungs feel over exerted. It feels like no matter how long I sit on the bench I don't fully recover the rest of the game.
Specifically, I will be coughing and out of breath, feel a burning liquid feeling in my upper chest (right around the bottom of my chest), have a taste like blood in my mouth (never found blood). Additionally later in the games I will feel a little nauseous and sinus pain in my forward and what I find particularly odd is that my ears feel blocked like I increased altitude on an airplane.
After the game I feel like my immune system is down, as I definitely have post nasal drip; but that goes away the following day.
The only thing I notice is if I do real good warm up and a get sweat going before hand my body recovers a little bit better during a game.
