Good luck with your disability claim. I have been fighting for disability for 9 years. I am on my 3rd successful appeal. Get all the physical proof and tests you can, or the judges won't rule in your favor. Use an attorney; they collect a fee only if you win. It is hard to slog through. Good luck at Mayo. I was referred to the Diamond Headache Clinic in Chicago, but I found that they offered only 1 procedure I wasn't already getting, are anti-pain meds, and out-of-network for my insurance. Research what Mayo offers you before you seek treatment there, and see if your insurance covers Mayo. It is extremely expensive to go out-of-network, and travel costs and accomodations for you and a companion are not covered. They may, however, be tax deductible depending on your circumstances.
