So i usually do light weight lots of rep workouts. But i just signed up for gym and i am doing cardio. Today was my 3rd day in a row. And man my f u c k i n g shin just seems like I got bashed with a bat on the inside of my right calf. Any remedies or solutions? I try to tell myself while im running and feel that pain " pain and discomfort is getting the weak out " but shit that shit hurts.
