I am having intense pain which makes me unable to walk whenever I run or jump in the inner side of my shin area. This has been there since last winter, didn't happen in summer, now it again came and it persist in this summer too. I did an xray but no abnormality, was given vitamin d tablets and have already completed the course but no relief, I don't feel any pain while walking, but when I run for about half an hour it starts, not as soon as I start running but gradually comes, same area everytime.
