Ouch! Hope you feel better soon.
Worst accident I heard that happened to a friend of mine was on a ride called the Roter. It's a cylander that spinds around very quick, so much so it makes people stick to the walls inside. Then as your stuck to the wall while spinning the floor drops two feet.
When the floor came back up his foot got caught. It was so bad they almost amputated but managed to get it out and eventually it healed fully though he does have a nasty scar there for life.
The ride was shut down indefinately and his parents sued the park. Fortunately for the park this was around the early 90's before people seeked insane settlements. (and also, lawsuits aren't usually as bad up here as they are in the US) Think they got around $50k.
