I suspect I have Lupus and my ANA blood test just came back as positive mixed homogeneous and speckled titre 1:640. Fatigue is debilitating and my legs have been heavy and ached for 7 weeks, along with my fingers (I've had this on and off for 3 years). I'm a runner and I want to continue to exercise at a low intensity, but I'm worried that any exercise will lengthen and/or worsen symptoms. Does anyone know if this is the case? I'm sleeping so much, but at the same time I don't just want to lie down and let Lupus take over my life.
