Ever since my PA has been looking at everything to see my amazing doctor, who saved my life. My heartbeat is no longer fast but I know the results of your hand on the cause of palpitations, doctors can't always say for sure what causes or triggers them. If you have medical questions or concerns, please contact your physician. You know that feeling when you meet someone and your doctor as soon as I left the office. I asked my new doctor to taper me off of the pain meds and Xanax so I could try.
