<s>[INST] I'm 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, don't exercise and have a very poor eating habbit.  I've tried antacids but with no luck.  The heavy, tight feeling just won't go away and now I seem to have a headache along with it? [/INST] HelloThis 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 likelyYou need to see a doctor right away for an exam and a cardiac workup </s>
