Mayo Clinic in Rochester, MN

Has anybody been to a Lyme specialist in Rochester, MN??  My local doc finally referred me to the rheumy dept over at Mayo because they can't figure out what is wrong with me. I have migraines, aches in my bone and joints, fatigue, memory problems, vision changes + more.  All of the signs that point to arthritis, ms, fibro, cfs, lyme, etc.  Everything that they have done here comes back negative - they think it's in my head.  I have had three "flares" in the past year and they last about a month. I am 35 years old - the nurse actually said yesterday "maybe it's just part of getting older"!!!  I am not that old!  I am not overweight either.  I am hoping that they have a good lyme doc at Mayo that could actually tell if lyme is what I have or not.  Anybody have experience with a lyme doc there?
