That isn't 100% correct. At least not in every sense. I was diagnosed with Rheumatoid Arthritis a few months ago, and life has been full of agony since then. I thought that things were bad enough when I was diagnosed with Multiple Sclerosis some 6 years ago now, but this just recently crept up on me and struck me with full force. I wake up as a cripple a good 70% of the time. Barely able to walk. I have to clearly analyze how I'm going to stand up after my morning shit. It's the worst. And it was amazing just how fast it came on. I had some routine stiffness. They gave me a few blood tests and I was diagnosed. Then I began taking a prescription medication at the rheumatologists request. Ever since then... Ugh, not fun at all.
And to think that I'm only 32. My wrists, elbows, knees, fingers, toes, ankles... fucking EVERYTHING hurts. But not my back or neck, so that's a plus.
