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. Her office tells me to go to ER is symptoms get worse WHICH I DID...then ER tells me to go back & see cardiologist. I'm also on 240 mg of Cardizem. I'm tired of feeling this way w/ no answers. Any advice would be appreciated!! Thanks!
