question: I am Arnab Basu, 33 years of age, have been suffering from pain on smaller joints of finger of hands and feet. Doctor has diagnosed it as Psoriatic Artharitis. Generally pain occurs once in a week and sustains for 2 days. I have just started taking Sazo 500 (twice daily) and Naproxen as SOS. My questions are: 1) Whether I have to take those medicine life long for arresting pain or inflammation? 2) What are the possible side effects of these medicines?
