What can happen is the shin muscle is tight and pulls away from the shin bone.

To warm up, just walk for a minute or two, to get the blood flowing. Stop. Then do some light stretches. I can PM you specifics if you need them. Then back and do yoru walking. Start flat and gradually work up the incline. (over days, weeks)

You need to give the shins a rest. Cold or cool packs if you notice any swelling. Otheriwse a nice warm bath with epson salt. Don't get back on the treadmill until all soreness is gone.

Ok..Personal Trainer Monkey off her soapbox.
