OK so, I am 24 and I have this skip beat then a hard thud in my chest, I can go months with out it then something triggers it and I have them multiple times during the day or night, I have noticed that I get a strong urge to burp. I never had these till after my son was born in 09. I've been to the heart Dr and he said I'm fine, I've been to the er so many times and had ekgs done and everything. I do have high blood pressure and anxiety, I dont have any other symptoms than the skip then thud. It so scary, I'm scared imma fall over dead from heart problems. Does any one else have this or anything?? Is it normal?? I and hyper aware of my body and its functions I've been told I'm a hypochondriac by everyone I know.I just need to know others have it also.
