What to expect when going to a rheumatologist the first time? And Fibromyalgia?

Hey all, I'm going to see a rheumatologist tomorrow, for suspicion that I may have fibromyalgia or similar issue. What do they normally do right off the bat for you besides the usual paperwork, medical history, etc?

Also, for the medical community, these are my symptoms, and odd things that go on-
-poor sleep / odd sleep patterns
-stiffness
-of the typical 18 tender points, I have 10
-muscle twitching, especially in the eye area
-experience numbness in pinkys and ring fingers of both hands
-mitral valve prolapse
-eczema
-bone pain in one foot, but there's no damage, no injuries occurred
-joints crack often
-constant tense muscles in my back and shoulders
-with flare-ups, pain is in the flank area- mimicks a severe kidney infection, when I go to the ER, my white blood count is through the roof, but once the pain subsides it goes to normal without antibiotics, accompanied by nausea and vomiting
-occasional constipation
-constant pelvic pain
-migraines
-dizziness
-difficulty concentrating
-fatigue that makes it difficult to function
-absolutely awful menstrual pain
-seasonal allergies
-breathing- I sometimes catch myself not breathing enough in a way, almost like I hold my breath subconsciously
-high stress levels and anxiety

This is what leads us to believe it's fibro, thoughts? Or does it sound like something else that I should bring up at my appt?

Luckily, I did get as far as being prescribed Lyrica by my doctor, this has taken away a lot of the pain, and I haven't had a flare up in almost 2 weeks (before then, I was having one every few days for months).

Thank you for your insight in advance!!
Heather- yes, everything else has been checked, and all tests come back normal. No evidence of stones, ultrasounds are done with every episode. No protein or anything else that would signal a UTI. The episode simply mimicks an infection- this has been determined, every time it happens it is proved that even though my white count is up it's NOT caused by infection.
