I have been having chest pain, palpitations, neck pain, jaw pain, weakness in legs, headache & dizziness. I have a pacemaker b/c I have complete heart block. Pacemaker is working ok. I went to ER last night...they did bloodwork, chest x-ray & EKG...kept me for overnight observation & said I was fine. I DON'T FEEL FINE!. I'm exhausted all the time....have appt w/ cardiologist that i can't get moved up b/c she's so booked.
