Oh no! I hope it's healing okay?

It sounds like you should have had an accident report filed, just in case you have any problems with it later?

I have had minor accidents at work but nothing serious.

When I was a student I once fell forward down stairs at the hospital where I was on placement - stuck my hand out to grab the rail jerked my thumb back and sprained it. I didn't report it but should have - the joint is still a little tricky over 20 years later.

Another good reason to report is for future prevention of more accidents - it gives your employer an opportunity to spot where the hazards are and remedy them.
