Don't confuse Shin splints with Compartment syndrom. Pay careful attention to your foot strikes while running.
Yeah but I'm not having any fluid buildup or swelling? isn't that one of the primary symptoms? and since I bought a new pair of shoes, and don't run on hard surfaces, It's only sometimes in my right tibialis, and it subsides after resting/sleep .. i've had ankle problems too, my range of motion is more than normal in my ligaments, and know how to strap them etc etc, but I just can't see the need to for cardio on grass. Thanks for the comments and advice though!
