Has anyone been to the Mayo clinic or Cleveland clinic for pots and/or other comorbidities?

What was your experience? Is it worth going?

Also, are there any POTS specialists (ideally who are knowledgeable about pots comorbidities) in the eastern part of the US that are worth seeing? I have severe pots to the point it's hard for me to move or walk anymore. I also have small fiber neuropathy, gastroparesis, severe chronic constipation, and intracranial hypertension that's causing a lot of problems and no one locally has been able to treat them effectively. I have some other issues that have no known cause - a few of those being severe shortness of breath, chronic pain/an undiagnosed connective tissue disorder, and muscle weakness. And a list of symptoms that's a mile long. I'm to a point where I can't function anymore and haven't been able to for about two years, everything just keeps getting worse. My family is willing to cover the costs of going out of state, although ultimately they'd have to agree on where we go.

I'm wondering what the best place is to go for undiagnosed issues that are likely comorbidities of pots and these other conditions, and for treating the ones i do have. Especially pots itself, of course, as that's one of my most disabling conditions, and if I could get rid of any one thing somehow, it would be pots.
