Hello Dr, I broke my ankle back in December 2013, and got better around May 2014, so I have been pretty much immobile for about 6 months. I believe I developed Sleep Apnea, and that is my question, do I have Sleep Apnea, or something else? Symptoms: When I try to sleep my lower throat/chest area gets tight and my hearts beating fast as a result of lack of oxygen, because every time I try to fall asleep I wake up gasping for air. I eventually fall asleep after twisting and turning, and sometimes these episodes happen, and sometimes not where I can sleep fine. I am wondering if this is due to immobility? Thanks.
