Hi, Norman.
With young men who are very active physicially, I tell them if this is the first time, and it does not persist, don't worry. If it does persist, see your doctor.
However, at your age (and you're a kid compared with my 74 years), you should play safe, and as
this web page urges, see your physician now.
Doctor Nash
What I tell you is what I teach. I'm here to help improve your quality of life, and I'll work with you as long as necessary to help you.
