Sjogren's Syndrome is an inflammatory disease where our own immune system destroys cells in our EXOCRINE GLANDS. The damage occurs mostly in our SALIVARY and TEAR GLANDS and it is a lifelong condition. In some cases other parts of the body are also affected, such as our BLOOD VESSELS, THE NERVOUS SYSTEM and ORGANS SUCH AS KIDNEYS, LIVER, LUNGS, THYROID AND PANCREAS. It can also affect our JOINS AND MUSCLES causing MUSCLE AND JOINT PAIN ( FIBERMYALGIA).
