hey guys been training mma for a couple years and for the last 4 or 5 months my shins have been hurting but dont have any bruising or anything. Ive been powering through it but even tryed taking a couple weeks off, still doesnt help. Even just poking the bone with my finger causes pain. Doing any kind of blocking is out of the question, its getting hard to hide the pain I thought my shins were supposed to get stronger, whats the deal here? recommendations?
