Shoulder pain from throwing?

During the game I threw the ball and I felt pain in my shoulder. Its been a few weeks and the pain still hasn't gone away. Every time I throw the ball it hurts from my shoulder blade all the way through to my deltoid. I need it to heal because travel softball is already starting. When I hurt my shoulder i was a catcher throwing the ball. And for travel im playing 3rd so i need my arm back. I would love to throw the ball the way I used to without any strong pain. If your advise is resting it i already tried that. And it seems like it keeps getting worse. I tried throwing again today and all i felt was excruciating pain and my shoulder cracked a lot. Please help!
