Does anyone know about bechets disease?

Rare & tricky. Behcet's is a serious autoimmune disease caused by the body's attacking heat-shock proteins. Almost all patients have white sores in the mouth, and often on the genitals. Arthritis &/or inflammation of the eye are also common, and since the disease involves blood vessels, almost any other organ can be affected. A needleprick may create an ulcer. See a specialist for treatment.
