Any suggestions for a knowledgeable doctor in Illinois? I have wasted my time for the last time going to one who knows nothing about the related issues that go along with chiari. My son has random pains, not life altering, but still complains about pains & also his bones crack alot. Yes, he's active but this doesn't seem normal to me. And yet our neurosurgeon couldn't tell me about any sister issues & says his chiari is fine.
