What causes dry eyes dry nose and headache?

These symptoms are vague, but one disease that can cause them all is called Sjogren's Syndrome - one of the most frequently found autoimmune diseases. Antibodies attack the moisture producing glands of the body causing them to dry up. Testing will often miss this disease until the symptoms have been long-standing. For appropriate diagnosis and treatment, please see your physician or headache specialist or rheumatologist.
