It feels like your heart is in your stomach beating? You need to see a doctor, it may be nothing, but it may be an aortic aneurysm, which is a "weak spot" in the aortic artery, if that's the case, it can be dangerous. Please see a doctor.
My stomach feels heavy and tight when I am laying down to go to sleep. It doesn't hurt. It also feels as if my heart was in my stomach, beating. Any ideas what might be wrong with it? Its been going on for a couple of weeks now not sure what to do about it.
Sounds like you ate too much
Maybe you just got your heart up throwing back the bedsheets
I'd see a doctor though if you were unsure
Stomach firmness ( hard), loss appetite, expelling lot of gas, bloated ,
not able to move bowels. Sounds like you should get medical attention.
