Oh, goodness, ! Dealing with Sjogren's syndrome on top of Lupus is no fun. You're definitely not the only community member here dealing with this double whammy. I wanted to share this information on Sjogren's (and how to treat it), but I know you may already know all this stuff, so apologies if the information is redundant for you -- https://lupus.net/living/sjogrens-syndrome-connection. I hope you are able to get some relief from the painful mouth issues very soon!
