This sounds like sjorgens, sjorgens takes a special blood test. It will not show up in a regular blood work tests. I was diagnosed about 15 years ago. Sjorgens is in the lupus family. I am now 62 years old and in the past few years i have started having severe faigue, and in the past couple of years i am now having skin problems with it…break outs and itching and burning, i have an appt with my rh dr in a few weeks. You need to get an rh dr. There is also meds for the dry mouth and you need eye drops evey day for the eyes…my dr recommends restasis but my ins will not pay for it so i use eye drops called oasis which i get from the eye dr. The extreme dryness in the eyes can cause damage to your eyes.
