I'm 52 and was diagnosed with lupus 4 years ago. Fatigue is definitely a huge symptom with lupus. Fatigue so profound that it is like one night's sleep is often not enough.
I, too, recommend a rheumatologist because their speciality is arthritis. That's also the major complication most lupus patients have. I get the best care and most understanding from a rheumie. A rheumie does not replace your regular doctor, but is an additional doctor for caring for the arthritis or the arthritis from immune system problems - lupus or whatever.
If you were in Waco, I'd recommend the best rheumie in the world!
I wish you well! Barbara
