Welcome to WHL. You've come to the right place for information and understanding. If you read through the threads, you'll find that many of us have been through much the same as you. Often it can take a lot of complaining to a lot of docs before getting the correct diagnosis and medications. Once your tests are back, if your doc doesn't recommend a rheumatologist, you might want to look for one. They are the real experts with autoimmune problems, as I'm sure you've read. Just beware, since there are good ones and bad ones out there. Keep trying until you find one that you feel comfortable with.
What part of Missouri are you in? I used to be from Missouri - I grew up near St. Louis and went to college at SLU. We've also lived in Columbia, Mo. You should be able to find great docs in St. Louis, with SLU and Washington U. having such great medical facilities. Of course, Kansas City Mo. or Columbia should also have good ones. Thanks to the Air Force, it's been a long time since I've lived in Missouri.
