Thanks for the reply, texasmary.
I always thought that in most autoimmune diseases that there would be some form of pain, especially in the joints? I have never had joint pain...although my joints do snap and pop during the course of normal movement (my hips make a weird--and loud--'snapping' sound if I extend them a certain way and my toes crackle when I walk). I have an appointment with an internal medicine doc on the 25th of this month, so I will ask her about my symptoms and see what she suggests. I also have an allergy appointment this month, so I will see what they think about the dry eyes/bloody noses/dry mouth too.
I will keep you posted.
