ankylosing spondylitis
"I have ankylosing spondylitis in my heels, fingers, shoulders, neck, shoulder blades, hips, front ribs and spine.  It started in my lower spine 42 years ago. After recently having had a bacterial lung infection for a 5 weeks, and walking about 3 kms when I was well again, the pain all over was excruciating. I had a Voltaren injection 5 days ago and have been pain-free since then. No side effects at all."
