I've contacted the Cleveland Clinic. I don't need a referral from my doctor to be seen and their Rheumatology department is rated 2nd in the country. What I do need - and what my doctor's office is trying to get - is authorization from my insurance company. I've been blocked at every corner - at least that's how it feels right now. Please send some good thoughts that the insurance approves this and I can be on my way to finding some answers - and some hope. TIA.
