Yes I've had the test for sjogren and I don't have eye problems . Its a real mystery and thats why I'm left on my own. I can't find a physician interested enough to look beyond lab work. All labs and my extensive workup was normal except skin biospy. Strangely the more severe my fatigue and exhaustion the less trouble I have with pain or any PN symptoms. Maybe its because when I feel this bad I can't do anything. It does seem that the more active I am the worse my PN hurts.
The only other thing is my skin looks 20 years older than I am. Its dry, wrinkled (arms and legs) and that actually was my first PN symptom, very dry skin an my legs.
