I read in the FAQ that you shouldn't roll/beat your shins with a rolling pin, what are the reasons that you would not do this? My shins are in pain for kicking the bag and sparring parteners elbows and knees and I am looking for the most effective ways to make my shins hurt less. Several people told me to roll my shins and it would kill my nerves and stuff like that but I just want a little more explanation. WWWD? (What Would Wanderlai Do?) Thanks in advance for any help.
