For two weeks I have been feeling weird. It started once or twice a day and gradually getting worse. It feels like blood gushing to or from my heart while at the same time I get very faint and tingle throughout my body. Hands, arms, legs, feet. It all happens at once and feels like a circuit going out for lack of medical terms. My head and chest have pressure. I am now having this hourly at the very least and physical exercise makes it even worse because I tried that thinking that it may be stress. I am tired and get confused when it happens and having a hard time keeping up with everything. when it passes I am fine for the most part until it comes on again. it comes on fast and is worse laying on left side. I get pain then.
