Hi Matt....been wondering how you made out. Good that you are seeing a rheumy...they will do a very thorough exam, looking at your skin, your joints, range of motion, take a detailed history of your symptoms (when they are worse, what makes it better etc.) and will more than likely draw labs to check your immunological status (ANA, Sed rate, CRP, lupus panel, RA panel....whatever they feel is necessary) to see if you have an underlying problem that is making your pain that much worse. I would ask them what they feel the pain/CF link is and what they do to treat that if indeed it turns out that is your main problem...hopefully they acknowledge that some of the pain could be from an inflammatory process because of the constant infections in your lungs.
Definitely write down any questions that pop into mind, also any symptoms and when they are the worst, what makes you feel better etc.
I wish you luck and I hope that you finally get somewhere. Sounds like this new hospital was a good choice for you.
