For the past 1 month I am having severe joint pain. All my small and big joints have been afftected, worst aremy both knees and the small joints of my fingers. Blood tests for RA, Anti CCp, DS DNA, ANF show negative results. My doctor has prescribed Saaz D , Amitrin and HQSD. My question is that my RA test is negative then also should I take Saaz D? Will I get benefit? Does it have side effects?
