I have 2 sons, ages 16 & 20. The 16 yr old has been positively diagnosed with AS. My 20 yr old has not been tested yet; however, my Rheumy believes he has it too. He has been stiff every morning for at least the past 4 years & has other symptoms too. My 16 year old was going to a chiropractor occasionally because of back pain. My sons' AS was suspected after I was diagnosed with AS less than 3 months ago. My son's are not taking this seriously at all. They believe everyone has stiffness in the morning and pain in their bodies. I can't convince them otherwise. Does anyone else have a son or daughter like this?
