Muscle balance is something that is constantly happening in our bodies. there are agonist/antagonist interactions that allow us to sit and stand upright. The front and the back muscles work opposite each other. When the pec muscle is divided (or even torn or even over worked) the opposite muscles (the trapezius, latissimus muscles) can go into overdrive, trying to balance the chest and shoulders. Sometimes we "splint" the sore muscle by tensing up the related muscle. To be honest, the best treatment is warm compresses and a nice back massage by a very gentle person. This will help relax the pec antagonist muscle in your back.
