I have recently been diagnosed with a 3cm hiatal hernia, i am on Omeprazole 20mg a day which helps with heartburn but i still have chronic belching. For about 6 months now i have been getting a tightening/crushing type pain in my chest at rest. It can last anywhere from 2-10 minutes. It often wakes me up in the middle of the night, i don't have any heartburn or burning sensations with this pain. I am wondering if a hiatal hernia could cause this or if it could be something more serious? I have had multiple ecg's, all normal and 24 hr holter monitor which did pick up a few ectopic beats but i was told these were benign. I have ectopic beats every single day, sometimes hundreds. I am waiting on echocradiogram. I am 32 years old and used to be very active but have gained alot of weight in a small amount of time and nowhere near as active now. I am scared to exercise as it can trigger the ectopic beats. Any help would be greatly appreciated, thanks, Dan
