Can sleep apnea affect daytime breathing??

So I have been diagnosed with sleep apnea and I’m currently waiting on my equipment. I have noticed I am getting a weird feeling in my chest on and off throughout the day. It’s not a pain but just a uncomfortable feeling. I also have been getting short of breath and anytime I do an activity I’ll start breathing hard. I had recent bloodwork everything was fine I had an EKG that was also fine. I don’t have any other health issues that I am aware of. I do suffer from anxiety that can be pretty bad at times. But during these moments of shortness of breath and chest discomfort I am not always feeling anxious they just kind of come on randomly so I don’t know if I can blame anxiety or not. All experiences and advice are welcome. 🙏
