Hello. aguillory
Allow me to welcome you to the forum!
I, too, am sorry you've needed to find us but very glad you did. You've come to the right place for information, guidance, and some encouraging support. As Abbey mentioned, this is a group of really great and helpful people.
I can't suggest what the darker skin patches may be from, could be a wide variety of things. I apologize; that's not a good answer, is it? Certainly something you may want to ask of the rhuematologist when you see them.
My best advice for the first appt. is to tell them ALL your symptoms, no matter if you think they are having a big or small impact on your life. A short summary should do, since these docs seem to like things "short and sweet."
Take any records of blood tests or other findings, and ask where they think you should go from here and what they would suggest next. They should take your concerns seriously and listen to you. Sometimes that's not the case, and if so, you may need to find another doctor who will.
I know the search for treatment can be aggravating and time-consuming. Please keep us posted, and feel free to ask anything at all. We'll do our best to help!

Again, welcome! We look forward to hearing more from you.
Melinda
