Nothing major. Fractured two fingers of my left hand once and had to have them immobilised for six weeks. But what made the experience a bit more painful is that I did not go to the doctor right away after the injury and the fingers ended up in wrong positions, so they had to forcefully straighten them at the hospital when they were treating me.
And I had some surgery done on my jaw a few years ago and ended up with an infected jawbone. The infection compressed a nerve -> agonizing facial nerve pain for 2 months. The pain slowly went away, but I still have a completely numb spot on my jaw.
