Shin Pain

I have shin pain also though not a severe as yours sounds. I was given an exercise that helps me a lot. I lay on my back and pull one leg to ward my chest with my hands holding behind the thigh. Then push against my hands for about 5 seconds, then hug the knee to the chest for about 30 seconds. I do 3 repeats on each side. When you limp it’s like stepping in a hole and throws your back out of balance and this exercise balances the back. I have pretty significant knee OA. Hope this helps.
