Looking up Steven Pete and assuming there probably aren't two 30-something pain-insensitive Steven Pete out there brings up http://www.thefactsofpainlesspeople.com/Steve.html which notes that "Visits to the Emergency Room and long hospital stays were quite frequent for my brother and I." and a number of other injuries-related notes.

The article notes that Steven Pete's congenital analgesia was discovered after his parents found him "chewing on [his] tongue" which I assume is to be interpreted more or less literally (though at 4 months old hopefully without much damage)
