I don't know anything about the neck palpitations...sorry. Things like that are very scary and can be alarming and nobody seems to have the answers you're looking for. I suffer from heart palpitations and have so for a few years. I've been through the standard tests of EKG, 24 hour heart monitor, ultrasound, stress test and nothing could be found. I also suffer from chest pressure most of the time so my doctor had me do an upper GI, which revealed mild acid reflux and a small hiatal hernia. No treatment was done nor suggested so of course I feel like a nut. I exercise quite frequently and a very high intensity and don't seem to have any problems but still feel periodic heart palpitations (5-10 times a day on average). I just want a medical professional to tell me I'm not crazy and to actually diagnose me with something.....this can't be normal!!! I also suffer from hyperparathyroidism and hypercalcemia as a result. Once again, no doctors have explained much about these disorders. What I have learned has been mostly from the internet (scary!!) Can someone please help!!
