The human body is amazing. If one muscle or joint is not working optimally, the body can compensate by using a different area. You can get by for quite a while without a problem. Then, seemingly out of the blue, your shoulder hurts. You didn’t even do anything! And then your back starts to hurt. And then you notice, your knee feels a little strange. What is happening? You are falling apart!
Actually, this is your body telling you that you need to stop and reassess. Painful movement means that something is not moving correctly. You must work on correcting this pattern or it will inevitably lead to something else hurting.
