Heartburn or just bad pain?

So there has been a bug going around when it came down to my son an I having it we got over it pretty fast but ever since then I've have this pain below my chest, in the middle of my bra line. My friend said it could be just bad heartburn but it's not a burning feeling, and I haven't got heartburn since I was pg with my son 4 yrs ago. I've took tums and they don't help. There is also upper respiratory infection going around as well. Could this be related? I'm confused. What do you think?
