I have just started to notice it getting harder and harder for me to breathe. I notice it when I'm sleeping, I tend to sleep on my side and I feel as if I take really short breaths and I do not find it hard to take full deep breaths. I feel as all of this is causing me to be a light sleeper and therefore lose alot of sleep and become tired on top of the little amount of oxygen I seem to be getting with my breathing habit. I try to sleep on my back, but I usually wake up due to discomfort. I have been trying to find similar symptoms online and all that I could find was possibility of asthma and possibly tight back muscles. I have an average build and I find myself to be fairly healthy. Please let me know if anyone could help.
