some vs. any
I've just learned the some vs. any rule. It says that 'any' is used in negative sentences, some is used in positive sentences and both 'some' and 'any' used in questions.

But what we are to do with such examples as
'Talk to your doctor if you have any questions'
or
'If you have any such knowledge'?

Probably the rule I read was not complete.

Answer

Any is used to show indefinite or unknown quantities or an unlimited entity.

"If you have any questions..." is a hypothetical situation. 
You don't know if there will be a question, and if so, how many. That's why you say "any."
