@Monika - I'm glad that you let the doctor lance your boil instead of doing it yourself. I have a good friend who wasn't as lucky as you are...or should I say, as patient and smart!
A friend of mine had a boil, and she just couldn't wait to go to the doctor. She picked at it and squeezed it so much it ended up bursting. She thought she was going to be fine after that, but she ended up with a really bad infection. Popping a boil actually pushes the bacteria farther inwards.
Anyway, she ended up on some serious antibiotics for awhile. I think if she ever gets a boil again she'll probably just seek medical treatment first!
