One year before a pain started in the left side of the chest.. which was felt in the left hand and backside of the arm.. there is a pricking pain in the breast and chest area.. after three four months i started to feel the pain in the right side of the abdomen.. which was felt in the right leg and backside.. it lasted for 7-8 months.. I had consulted doctors.. did scanning.. but the reason was not identified.. now again the pain started in the left chest area.. I even wake in the sleep due to this.. I'm fed up with this.. I'm much disturbed with this pain since an year.. please help
