What kind of specialist do you see for CFS?

Hi all!! I'm 27 and suffering from fatigue and insomnia for almost 2 years now. I wondering what kind of specialists to go to regarding CFS? I had my first appointment with a rheumatologist on Monday for possible fibromyalgia, is he who I should speak to? I'm looking to also get a sleep study done for possible answers. Thanks in advance!!

I would talk to your rheumatologist about possible CFS. If you don't get anywhere with that, you could talk to your GP. I hope you get some answers.
