welcome to H C M
i think the diagnosis is confirmed with the help of investigation as you stated.tab sazz is drug of choice in this case.ask yours doctor to add more drugs to control the disease,as early as possible.it is always better to go for x rays of spine & bilateral s i joints.being fine with adjuvent therapy does not mean that disease is control.pl take regular medicines--under supervision of yours dr.homeopathy
can make you little comfort-as it is a autoimmune disease
..the .control is possible with these drugs only.
