i am experiencing a very strong heartbeat in my throat (pulses with heartbeat) and lasts for days and then subsides to bearable. Laying down to sleep starts it up all over again and causes me to break out in a sweat all over my neck and head (literally wet) and is now a continuous cycle at night. Last couple of weeks i can feel a pulse in the front of my throat. I dont feel anything going on with my heart when this happens. fluttering in the throat, neck or chest need not cause you undue panic. It is a commonly seen manifestation in a lot of people on the other hand, if the fluttering is becoming apparent on a regular basis and is associated with any other symptom, you need to visit your doctor.
