Over the last year or so my arms and legs have been 'falling asleep' a lot easier and faster. Also 2 years ago I was injured during rugby (I believe I cracked/damaged cartiledge in my chest wall) and my chest got inflamed from the inside and ever since then I have been having a hard time trying to breathe and it feels like I could pass out from going up some stairs or climbing a hill.

I have been to doctors nearly non-stop and none can give me an answer. Im scared it something serious and goes hand in hand with my falling asleep hands and feet. Could it be a heart problem? I'm hoping not, but if you know what is going on or know something may help, that would be greatly appreciated

:) thanks
