If you are having chest pains get to the doctor or go to an ER. If you are having chest pains and posting on internet forums then you don't take them that seriously. Grok didn't have a doctor but that doesn't mean you shouldn't. I had chest pains when I was 25, but it was a muscle pain form a twisting motion I was doing as part of my job at the time. The doctor confirmed by EKG. I had chest pains in my mid 30s from twisting my shoulder taking off a heavy backpack. (which probably aggravated the muscles twisted when I was 25). I had chest pains in my mid 40s when I was following the McDougal diet. It was GERD. McDougal will tell you his diet (ultra-low fat vegan) is the best cure for GERD. In fact the day I started to question McDougal theories was when I had been diagnosed as having GERD. I was giving a prescription for Prilosec and an information sheet (created by the maker of Prilosec) that recommended a low fat diet. I felt like screaming: "What the hell have I been doing for the past 10 years." This was just after recovering from my second cataract surgery in a year at age 49.
