question: Im 22 years old male. I have been having chest pains for the past 6 years every now and then and i always discarded it as gas. but for he past 6 months its been happening very frequently and stays for a longer duration then normal. I have been loosing weight too for the past 6 months.. close to 5 kgs. And plus for the past few days my left hand starts shivering mildly when i hold somethings like a glass or spoon or cup etc.  And i feel very sleepy most of the time inspite of getting a good 8 hour sleep.  I was just wondering what this could be?.. any thing major? .. i havnt got this checked yet.
