I started smoking when i was in class 6, but quit smoking from the first of this month. Last month i was admitted in hospital as i having breathing problems, bt in hospital they gave me sleeping injection. This year too i was admitted in hospital for same reason, the doctors said i was loosing my pulse, which was around 3-5bpm. But this time to, they gave me sleeping injection. Now again after a month since that incident i faced again the same problem, so without going to hospital i rushed to my brothers clinic, who is a homeopathay doctor. It was he who saved last time, as he poured one of his medicine in my mouth due to which i could start breathing again. And this time too, he Again cured me. Now its been 2 weeks after that, for the past 3days am having terrible chest pain, my chest feels heavy, having problem of breathing. My shoulders pain on alternate, and there a sensation of numbness and dull pain on the lower side of my hand. It happens only when am sitting or working but not when am sleeping. My brother says its due to gas problem when got stored in my body over a long period of time. But i fear that it might be the symptoms of heart attack. Please do help me out, as to what i can do to save myself.
