forgive my spelling i am not good with some terms and my hands dont follow my directions well.... i am suffering from psoriatic arthritus and some other possible chronic pain issues. i was having great success managing pain using etodolac and oxycodone. i almost had no pain at all. recently pharmacies in my area are despensing a brand that has an imprint of A333 on a oblong white pill. this seems to have almost no affect on my pain at times. i was getting the watson brand before this. my pharmacist asked me if i had a preference in brands, which i thought was an odd question. why would one brand have a different affect than another.
