Hi there, I would just like to say that I think this service you are offering to do is very caring, you must be good people, I am afraid I am having constant Chest pain/leftback/left shoulder/left armpit shooting arm pains for the past 2 years now, every single day. Some quick information about me: I am 20 years of age, I am male, I have a history of Benzodiazepam addiction but have now been clean for exactly 2 years. I used to smoke a lot of cigarettes as well as cannabis but no longer do, as these things GREATLY increase the shooting pain I get on the inside of my left arm. I have gone and done an EKG and it came back normal, the pain is never present as I am exercising but sometimes it may strike as I begin to increase my heart rate (and then disappearing) I HAVE noticed that in times of worry and anxiety, it is POSSIBLE the pain does get worst, but I have no way to tell. This is starting to become truly unbearable and I am scared shitless that I have heart disease. The pain can only be described as a GRABBING or HOOKING sensation when it comes to the pain in the left arm under the left armpit etc. and as a SHARP, sometimes DULL, STABBING pain all around the chest area, as well as on my back shoulders, and sometimes a very STRONG pain on my LEFT leg. Please doc, please tell me that there is no way a kid like already has heart disease? This pain is very real, and Nicotine makes it MUCH worst almost instantly. I appreciate your time and help, and I thank you in advance. Is it possible to have heart disease if I feel NONE of these symptoms when I am in the gym and working my heart at 150 BPM ? Only when resting....
