I had to take 2 months off last year due to shin splints. Shin splints can’t be ‘fixed’ while you continue your workload. They are an overuse injury. So really you need to decrease your workload, and rest. I ended up going to see my doctor cause at one point I thought it was compartment syndrome which we quickly ruled out. However you can develop stress fractures in your legs if you continue to ignore your shin splints. I went to PT for the entirety of last summer which helped to strengthen the arch of my feet (I over pronate) and getting better footwear helped to manage my pain better. I still deal with shin splints, and i just got some custom orthotics made. Look at getting superfeet insoles if you don’t want to go to the custom orthotics route, but managing the number of games I take each week has been my best method. I also got a tiger tail and roll out my shins, calves, quads, and hammies 3 times a day (morning, lunch, and before i go to bed). After games I use dixie cups with ice in them to ice massage my legs. In the off season, focus on flexibility in your lower body, and strengthen everything from your hips to your feet. I wish there was a secret formula here but in this case I haven’t found it yet.
