I zoomed in on the sore on the roof of my mouth.. My tongue has been giving me issues also. Is this sore because of a flare I'm in? Also I'm being tested for Sjogrens I failed the Salivary Gland Function test horribly. The radiologist interpretation was "Consistent with Salivary Gland Dysfunction "... So I'm not sure where these sites are coming from... Any ideas?? Is this a lupus mouth sore ???
