Why Frozen Shoulder should develop might seem difficult to explain because other large joints in the body do not exhibit this very painful and debilitating condition. Martin’s publications explain what is probably the main reason why frozen shoulder develops and how to treat that distressing condition. They also describe how to treat other shoulder problems. It boils down to this: other joints in the body have a defensive, braking mechanism built into the nerve reflexes around a joint to protect them but the shoulder joint does not and means that simple normal activity, such as combing the hair when there is pain, causes more pain and inflammation and potentially frozen shoulder.
