I have a female friend who has been suffering from Sjogren's Syndrome symptoms. While it has not been 100% established that she has Sjogren's Syndrome at this point, she has been suffering from the effects (dry mouth, dry eyes, throat problems, sleep deprivation, fatigue, etc.). Today, she had a CAT scan done to help diagnose her condition. I talked with her on the phone (she lives 800 miles away from me) shortly after she got home from the CAT scan, and she is in great distress. She says that she has absolutely zero saliva being produced (she was practically bone-dry before the CAT scan). Do you know if the CAT scan could have caused permanent damage to her salivary glands, or is this potentially a temporary condition that will go away?
