I'm wondering if anyone experiences something similar to me. I can do the rapid breathing either through my nose or my mouth. If I do it through my nose, I just can't get air as quickly, and if I really force it, I notice that for a few hours afterwards, my nose passage-ways will be slightly swollen and my nose breathing is restricted.

The same is true if I breathe through my mouth. If I'm really going for it and doing it quickly and aggresively, I notice my airways are inflamed and I have a slight wheeze for a short while afterwards.

I can reduce the intensity and I will avoid the side-effects, but then I also notice that the effects of the hyperventilation breathing is less. I won't ever get the tingly feeling if I do it in a more controlled fashion.
