                        I am asking for any information of anklosing spondilitis and any successful treatment or hospitals specializing in this disease.  My son, 29, was recently diagnosed with  AS.  He started out with iritis but  has had severe back, shoulder and leg pain since his early teens.  He is now  also having chills/hot flashes, severe  fatigue, weight loss, lack of appetite  and seems to be gettng worse.  He was   on methyltrexate but it made him sick. Please let me know any info on this.  Thank you.
