My 16 yr old son is now taking AS seriously after seeing our Rheumy. My son is obviously not as affected as your daughter is. The doctor put him on Naproxen 500mg twice a day. At this point, he isn't feeling any different, but it has only been a week. I'm totally confused about meds anyway. Some of the posts say NSAIDS make AS worse, but the SAA has them as usual meds prescribed for AS. I don't know what to believe. Good luck with the right meds for your daughter. I understand your concern.
