Digestive problems question

I've noticed that I get a lot of sharp, ping-y feelings in my chest. Sometimes on my left side, sometimes in the center. Obviously they freak me out, but I keep trying to tell myself that all my heart tests so far have come back with pretty good results. Anyway, they're scary regardless, but what happens shortly after the ping-y feeling is that I'll feel rumbling in my stomach and/or the need to have a bowel movement (which, by the way, sorry for TMI, has changed a lot in the past couple months and my gyne suggested possibly IBS) I know no one here is a doctor, but in personal experience, does this make sense? Does this happen to anyone else? I don't get the connection between my chest and my digestive system.

Okay, that makes a lot of sense. I took a long bath, which usually helps with stomach issues, and am feeling a little more calm.
