Difficulty Breathing
Breathing problems, particularly when sleeping, are a major symptom. There should be no discomfort during breathing when the muscles are relaxed. If you’re having problems breathing while lying down, sleeping, or even doing mild activities, see a doctor. According to the American Heart Association, blood pools in veins when it can’t follow any flow. This can lead to a build-up of fluid in the lungs, which can lead to cardiac difficulties.
