Yesterday, my fiance and couple of our friends went out to eat at a Mexican restaurant, I was eating a tortilla chip and one of my friends said something that made me laugh, while I was laughing, I could swear I felt a piece of the chip being inhaled, I coughed and coughed and had my fiance pat me on the back while I coughed to see if I could get it to come up, I took a sip of my drink and felt fine. I thought I had coughed it up. But that night, while driving home, I started to get a pain in my chest that felt like a combination of heartburn and an asthma attack ( I have both). I was able to sleep fine last night, but this morning I'm still having mild chest discomfort and shortness of breath. I also suffer from generalized anxiety disorder so when I told my fiance this, he said I'm more than likely panicking for no reason and making the symptoms up myself in my head. I do this often and am the biggest hypochondriac I swear. So, with it being almost a full day ago, am I okay? Am I panicking for no reason or should I seek medical help?
