Unfortunately you do not tell what kind of sport is causing you pain. neither what sort of movement. Neither where the pain is located. Neither if there is any radiation. If there are other areas of pain which might be related to the shoulder. What did the physio treatment consists of what sort of exercises were you given. What did the physio tell you the cause of your pain was. Is there a diagnose of luxation of your collarbone and how was this diagnosed. how long ago did you had your fall. Has it improved since.
Unless you give some more information a reply to your question is a shot in the dark.
