breathing issues?
Over the past month i have had on and off breathing difficulties. i suffer from chronic moderate sinusitis. so I am a big mouth breather. I worry its my heart but i have had that checked with a treadmill stress test a year ago and was ok. Had an EKG a month ago and that was OK. i did have bad bronchitis a couple years ago but cannot figure with my breathing is labored on and off? any suggestions
Also, i do not have a cough or fever
