Get the referral to the physio and then hope they carry out a good orthopaedic examination in order to give you and idea of where your pain is originating.
I like doing this with my hip pain runners - get a tennis ball - lie on your painful side and then place the tennis ball in to the muscles above and below, to the front and behing the hip bone and see how that feels. So much hip pain in runners comes from surroundin muscles/trigger points.
How is your lower back - any issues there? The physio shoulkd be able to examine this at the same time.
