I m a 21 year old male, I started sprinting as an exercise to keep my weight in check. I m about 5 10 and weigh around 65 kg. I started having pain in the inner sides of my shin bones of both the legs. I ignored the pain for first few days thinking of it as pain that usually follows when one first starts a new workout. But it became unbearable after a few days and I could barely run. The pain subsides slowly after resting for atleast 2 weeks but then when I started running again, the pain came back just as before.
