Ankle clicking

I have had problems with my ankle clicking for a couple of years now, however in the past year the clicking has become more frequent ( almost all the time ) and much louder. I have been to see my doctor and he sent me to see an orthotist. X-rays have been taken of my ankle and no problems were apparent, although they did say it was one of the loudest joint clicks they had ever heard. As I was born with one ankle slightly turned in, they made the assumption that this may be the cause of the clicking. Subsequently I have been given many different ankle supports and insoles to try out over the past year.
However none of these have worked and I now have terrible pain in my ankle and foot quite frequently. The Orthotist is at a loss, and says there’s nothing more he can do. I cannot let them tell me this as the pain is getting worse and as i’m only 17 now, I worry it will become unbearable in the future. P.s The only other explanation I could think for these problems is that when I was born my mother was told that my hip may have been slightly twisted during my birth. My mother was told that if any problems with my walking occured ( which they did – my foot turned in ) it would strighten out before I was 5. However it never did. I have told my orthotist this but he doesn’t seem to want to investigate into this theory. Can you give me any advice please, I don’t know what I should do next.
