Just because you had ITBS before doesn't mean that's what's happening now. "My knee was killing me" conjures up 5 or 6 diagnoses without even thinking too hard about it or being an orthopedist. It's kind of like saying "I'm sick. What's the best treatment?"
It may still be ITBS, but before you continue treating a potentially wrong diagnosis, I would see someone and get that knee examined.
