For the last 10 years and up until 1 year ago, I was competing in Master's Track and Field and running up to 6 mile road races.  I tore my hamstring, which side-lined me, and at age 70, it's hard to regain endurance if completely healthy.  But 6 months ago, trying to run, I just didn't have the energy to even think about running 1 mile.  Then about 3 months ago, I woke up in the middle of the night with the driest mouth I have ever experienced.  My tongue stuck to the roof of my mouth.  My eye doctor says I have very dry eyes, but I can't say they bother me.  sometimes in the middle of the night my eyelids are sort of stuck closed.  Eye drops do help.  Now,a s in the last couple of months or so, my elbows. knees. low bakc, shoulders, sometimes writs and fingers just ache.  No swelling, just joint pain and the fatigue continues.  My doctor thought Sjogren's right away and ordered all relevant lab work.  Evry single one, including the lab for Sjogrens itself, was negative.  I don't have any gland swelling or fever either.  Does anyone else have vague symptoms, but not all of them?   Do this sound like the beginning and it may progress over time?  I try to keep plugging alone and take ibuprophen, eye drops and mouth moistener, and drink lots of water.  I also nap.  but I'm used to being very, very active and all this is frustrating.  Any thoughts out there?
