Lately I've been waking up sometimes with this feeling like I am having a heart attack or feeling like I can't breath. I know I have sleep apnea but it never has gotten to this point. Wonder if that means the sleep apnea has gotten worse or something.

Anyone else have this feeling? I will either have this pressure sensation in my chest and at times, I may even feel like I am not breathing well and feel like I would pass out. Sometimes I wonder if I should get a second sleep study and see if I can get a breathing mask some people get in order to breath and sleep better.
