Seriously get him to push for a scan. He needs to tell them he is in agony constantly, can't dress himself properly, can't sleep properly, can't work, can't do anything because of the pain. If he has physiotherapy after tearing his ligaments, rotator cuff etc he will be out of action for a lot longer. He has to lay it on thick and get a scan because they will 'hope' that physio fixes it.
