Hi, checking in! I'm new here, not yet officially diagnosed with Sjoren's but on the way. I also have a genetic condition called MEN-1, which causes the endocrine system to develop nodules/tumors and the wreaking of havoc on hormones. I also have/had a congenital heart defect, an aneurysm in the Sinus of Valsalva, which is rarely found in time.
Overlapping of symptoms is something with which I'm familiar... I have a nodule on my sub-mandibular salivary gland (right) and extreme, debilitating fatigue, which is what is pointing to Sojren's. I look forward to posting. learning, and supporting!
