From last 3,4 months I am experiencing body ache, breast pain and my body becomes too hot without fever 10,12 days before my periods start and sometimes along with pain also experience flu like symptoms feeling of cold and fatigue. And my duration of bleeding has also reduced from 5 days to just 3 days with starting of these symptoms I really feel very uncomfortable during those 10,12 days before my periods because it pains and feel sick. But once the period starts all above symptoms and pain subsides completely. Is there any way to lessen those 10 days uneasiness because I feel so much uncomfortable that I can hardly concentrate on my other work till my periods arrives I am 22 and avg height and my weight is 64 kg.
