Sore, weak shoulder please help may be torn rotator cuff???

Im a tree climber and about Four days ago while in a tree i was almost in a sit up position when my shoulder kinda popped and when i looked at it my shoulder was completly behind where it was supposed to be...after i got down from the tree it went back to its normal position...Now 4 days later it is sore and feels like it could pop back out when i try to pick up something moderatly heavy...when i rotate my shoulder a certain way it sounds like the muscle is tearing......Any ideas if its a rotator cuff tear, ligiments, or dislocated shoulder???? its not a horrible pain but def. uncomfortable and very sore....Im not sure if its even back in the socket???? Thanks in advance
