I Popped my Shoulder out of Place

It happened on a saturday. I was hanging out at home, just having fun on my trampoline. My neighbors came over to hang out with me. My neighbor Jason told me that he wants to learn how to door a really good hand stand and be able to walk around doing it. So on my trampoline he was doing some handstands and I said," Oh thats nothing watch me." so I jumped of my trampoline and ran up the grass on my hill and once I was at the top I did a hand stand. I kicked to hard while I was doing it and landed in a brige. I am on a cheer team and I know how to do all this stuff, so it wasnt like I was just being stupid and wanted to do a handstand. Anyways I was like why dont I just kick over and warm up my walk overs. So there I did it and as i kick i was half way over and POP my shoulder popped out of place! "OUTTTCHHH!" I yelled, and fell on that very same shoulder that popped. Getting tearing my neighbors came to help. I was hoping it wasnt hurt. I started rolling it around and knew it was back in place but it was deffinatly hurt. The next morning when i woke up it was about eight in the morning on a Sunday. My arm hurt so badly i couldnt even bare it. I went to wake up my mom and tell her i couldnt even lift it up. It was so painful. So we drove to Providence hospital. After about 3 in a half hours of waiting we finially found out it was sprained and i needed a sling. I asked,"If its hurt how come it didnt hurt yesturday and i was able to move it ?" She said," Just like a sore burse it doesnt hurt until the next day." So the rest of the week, i had a sling and couldnt cheer at our football game that week.
