Im 43 and about 2 weeks ago I got a weird sensation in my chest, the middle.  It was a heavy tight feeling. I dismissed it and it did go away, however the next day I ate some popcorn and it came back, also after eating a variety of foods even licorice?  I do smoke about 6 cigs a day, I am overweight, dont exercise and have a very poor eating habbit.  Ive tried antacids but with no luck.  The heavy, tight feeling just wont go away and now I seem to have a headache along with it?
Helots could be cardiac in nature as in angina or even a heart attack. It might otherwise be gastric acid reflux but if antacids don't help that is less likely need to see a doctor right away for an exam and a cardiac workup
