POTS and fibromyalgia and dysautonomia?

I was just wondering, my doctor is saying I have fibromyalgia and I guess I am getting tested for pots. I don't faint so I am not sure why I am getting tested for it.

They also said I might have dysautonomia..

Any of you guys have this? If you do, please tell me about your story! I would love to know.

Thank you!
