Firstly i had chest pains but that was ruled out as no heart problem by doctor as normal because my ECHO 2D & HRCT scan report was normal and also i had ECG for 4-5 time within 3 months all was normal But Still sometimes i get chest pain like stabbing or sometime intense and sometimes i feel problem to breathe, my arms, joints usually hurts daily and Even i have back pain constantly every day I do even have stomach ache a lot and digestion is not proper at all. So what could be the problem.
