Can Sjogren's cause this type of pain? Unfortunately I was one of the lucky ones who developed bone tissue death (Necrosis) on both knees due to steroid usage. I would definitely discuss this possibility further with your doctor. A bone scan may pick on this depending on what stage the decease is, but usually the best test for this would be an MRI, its usually ordered after something's picked up on the scan. Hopefully its not anything like this, and hopefully you'll get a diagnosis and a treatment plan to keep you as pain free as possible. Please keep us posted.
