I can't help you with the lab results. However, 20 years ago I had thyroid cancer that took forever (and several doctors) to diagnose. I knew there was something wrong and kept going from doctor to doctor until I find someone who diagnosed me. What I was hearing over and over from docctors was, of course you're tired, you have a job and three children. I was tired because my thyroid had stopped functioning. (forgive the rant)
My symptoms were extreme fatigue, memory problems, malaise, weight gain, constipation. I would get lost on my way to work, fall asleep at stop signs, make stupid mistakes at work, etc.
With lupus and RA, I have similar extreme fatigue, joint pain and stiffness, headaches, muscle aches, gastric problems, and low grade fevers.
You mention joint nodules/stiffness. I didn't have those when my thyroid stopped working and I can't imagine how those could be connected to one's thyroid, but I'm not an expert. It sounds very much like you might have both. Have you seen a rheumatologist?
There is a huge range for "normal" TSH results and I do better when I'm on the high end. After 20 years I'm pretty attuned to my thyroid levels and you probably will be too. Ask your doctor what the normal ranges are and what your reading is. Once you get your thyroid adjusted (and it my be now) and still have the extreme fatigue, I'd be sure to see a rheumatologist, especially since you have joint pain and stiffness.
Mind you, I'm not a medical professional and this is just my opinion, but I do hope you get some answers. It's a tough road to get the proper diagnoses and that takes doctors who care enough to listen and try to help. In my experience the best doctors have been women.
I'd also suggest looking at a thread in this website that should be read by all news members. It's under "Resources" and is about the fifth subject down, written by AlwaysRosie and is entitled "Tips for New Members" You'll find it at the top of the main Lupus Page. Let us know if you need help finding it.
Good Luck and I'm glad you came here for help.
