Is this the first time you've experience this or did it happened before? Cause if it happened before it will keep on coming back until you have it checked up by a physician. Putting muscles to it without doctor's consultation will damage it more.
mine, it all started when i sprained my right shoulder trying to steal the basketball. it got inflamed. then laro, un na-sprain ulit. the next few time- it got dislocated during a basketball tourney. itgot locked & can't put it back. it got in again, after i relaxed. after the game, i can't even lift a glass. it happened more than 20x na. but the major-major accident, syempre sa basketball din. it was dislocated when i hit the forearm of my kalaban and at the same time pataas ung kamay niya. un. grabe, d ko mabalik for 5min or more. nahinto ung play. but when i was able to lower by shoulder, the rotator's cuff -napunta sa ibabaw ng dede ko. un nagpadala ako sa san juan de dios to reduce it. they injected me a drugs to relax, then they were able to shoot it back without add'l pain on me. they xray it- and good thing its-ok! so 1 month of rehab, then played tennis again. they advised me to strengthen it with dumbbells.
iba naman ung mga experences ko with my left shldrs.
but the good thing is di na nag-dislocate ung mga shoulders ko. reminds me of hitting the dumbbells tonight. hehehe
lessons learned: if it hurts- always consult a physician, and don't play with an injury.
