I have had a fractured sesamoid in my left foot for three years. I used to play hockey every weekend but had to give it up entirely due to the pain. Its not al bad though. If it doesn't heal at all like mine, you can learn to manage it. You can do pretty much anything you like if you are willing to handle a little pain and recovery time. I don't know if anyone has told you but there is like a 9months recovery period after surgery and then you are told that you can't do heavily pysical sports.
Too be honest with you while you're young (I'm 20) it is just as easy to deal with the pain, embrace it and review the situation when it gets unbearable. I did a 75km tramp accross some pretty rough mountains with my injury and while it hurt I still managed to keep up with the rest. The blisters were just as bad actually hehe
