I am a 36 year old female, thin and usually healthy. For several years now, I have been suffering with drenching night sweats off and on. All viral and parasite tests have been negative. In 2008, I was diagnosed with neutropenia, although my doctor can find no cause. This past February, I began experiencing blurry vision and pain under my tongue. The pain under my tongue spread throughout my mouth. The pain was terrible, but my mouth looked normal. I also began to experience pain in my lower right flank along with horrible nausea. I had a CT and an MRI, but they were normal. I recently had an ANA test that turned out 1:160 Positive. Could this be Sjogren's?
