sjogren's syndrome
"I have been on generic hydroxychloroquine now for 2 years.  I have primary Sjogrens and secondary diagnosis of Fibromyalgia. Apparently I had Sjogrens for over 10-15 years before doctors figured it out.  If the Fibromyaligia hadn't hit me 3 years ago I guess I would still be suffering. I take 200 mg twice a day and it has helped me so much.  I use it with Savella for my Fibro pain.  The only problem I have is a slight buzzing or ringing in my ears.  But I can work full time and have a normal life.  Still get occasional pain in feet and legs but all and all feel great."
