in oct 06 I had an operation on my right shoulder to correct an impingement. All went well and by Feb 07 I was back in full training. All was going OK until my coach trippled my swim sessions and distances! My shoulder is now complaining again - can the bone grow back that is taken away during the operation? What should i do? Should i carry on training as i only have to keep going until october and then can get it sorted or should i seek help sooner?
