So I am an 18 year old male in relatively good health (above average) and I ahve been running once or twice a week for the past 2 years now.
2 days ago, I went running and towards the end of my run (25 minutes in), I started having a very intense pain in my chest exactly where my heart is located. I still finished my run without slowing down because I thought that the pain was only due to the fact that I was making a cardiovascualr effort and that it would go away as I catched up my breath, but it did not. It decreased (went from unbearable to sharp) in the following hour but it reached a sort of plateau which I have been experiencing for the past 43 hours.
I am quite concerned as I was convinced I was about to have a heart attack. Should I worried and go see a doctor or wait a couple more days and see if the pain fades away? Also, it might be important to mention that I smoke cannabis moderately.
