Rob,
Sorry to hear about the unplanned perforation. Have had similar experiences, well, not quite exactly the same, but similar.
I am a member of the Texas Southern Baptists Disaster Relief Organization on an "on and off" (but mostly on) basis, and need to renew my training pretty soon to get back on, as I have been behind a few months....so am temporarily off the group again.
What I learned from the last time I served in a disaster trip (a flood) is "DON'T PUT OFF THE TETNUS SHOT." If it could POSSIBLY have been anywhere near as long as 10 years GET A FRESH TETNUS SHOT. It is not worth the risk!
Regards,
Stew
