Well i have been dizzy and i did my blood pressure and it was low. It was 79/66 and my pulse was 49. I just feel tightness in my chest ans my heartbeat feels irregular. I have had to stop several times because of shortness of breath.
Are you on any medications? Have you been on a low-sodium diet? If so, eat something with salt. It sounds to me like your electrolytes might be out of balance and that you need more sodium. Then call your doctor's office as soon as they are open in the morning. Or if your symptoms get more severe, you might need to go to emergency yet tonight.
