my shoulder dislocated

Last week i represented my university in Sukan Institut Pengajian Tinggi (SUKIPT) in Karate-Do event. Actually I'm one of the hope in getting medal for my university. But thing doesn't go like I wanted. Just before my game start, I did a little warm up with my senior. Unfortunately, during the warm up, my shoulder dislocated. It's quite painful and at that time medic team was not there yet. Luckily I corrected my shoulder by myself. Then when medic arrived, I went to them and they sent me to hospital for further checking.
