I am having severe backpain on my right side which intensifies when I take a deep breath ..I consulted a general physician 2days back and he prescribed medications for
kidney stones and asked me to take it for 3days.It's already been 2 days and still my problem persists.I feel more pain when I wake up in the morning that I need to crawl to get up from bed .This time I got my periods late by 7days and today is the 3rd day of my period.Pain is so severe like someone stabbing my back with knife.. Doctor what could be the cause for this pain???.....
