I was diagnosed with Sjogren's in the fall of 2012. I have been handling pretty well with medication. For the last month and a half I have had vertigo-type symptoms. After a few weeks of this, I took Claritin, as I felt like I do during allergy season. After a couple of days it cleared up, and I felt good until the last week or so, as it has returned occasionally. Is this a normal symptom (flare) of Sjogren's?
