Is fatigue normal with autoimmune disorders that are being controlled/treated effectively? I feel no better since starting med 8 months ago

Common yes normal no. Chronic fatigue syndrome is a multifactorial consequence of hormonal, immune system and nervous system dysfunction resulting from genetic predispositions and dietary and environmental insults. These factors impair the patient's ability to produce energy and they end up chronically fatigued. Your treatment may be controlling some of your symptoms, but it is not fixing what is wrong. Find and fix.
