I've a Rhuemy appointment this week and was hoping for some advice. I've been taking Sulfasalazine since January along with Naproxen. Over the last few weeks I have experimented by omitting the Naproxen to see if the sulfasalazine is working. The results have been extreme pain and stiffness. Does this suggest that the Sulfasalazine isn't working for me? Or that I should always take Naproxen? You see to my thinking if the Sulf is working I wouldn't need to be taking the Naproxen. Or am I wrong? Have any of you advice or experiences to offer me?
