Yeah, i had a lot of shoulder issues, and ended up getting surgery. My initial reaction is that it should be pretty apparent if it came out or not. Like the first time I dislocated mine imediatly I knew what was up and popped it back into place. In terms of what it feels like afterwards, yeah it will be really sore, you will probably be really scared/or it will be painful to move it much at all. Like serious limited range of motion. You might be more likely to hurt it or do it again, so I would recommend chillin out for a bit, and wait to see how it feels in a little while.
