Back to Work Again

I am trying to go back to work again after being off for another three days due to having to have a bad tooth pulled. The hole in my jaw is doing better but still sore, can't chew on that side of my mouth, and still taking what seems like way to many Advil. I am not sure they really beleived me at work, but I had a note from the dentist to verify that I had the tooth out. So what can they say. I would hate to fired for having a tooth out.
