Nothing too serious just brought my brother-in-law because he has a gnarly infection on his tonsils. I know better than to ever go to the emergency room unless it's a real emergency, but we've been to two other places and finally got referred to the ER.
They're going to poke his tonsils with a needle to release the puss and infection, if that doesn't work he may have to have them removed. I hear that's a pretty painful recovery for adults. I had mine out when I was five. I remember the recovery consisting of watching Thumbelina and my grandma making arroz con leche for me.
Twenty years later I'm still holding on to my tonsils. They were always fun to take for show and tell.
