I think staying on rx nsaids is prob a bad idea.
you should pay attention to your pain, maybe you are having more cortistol rebound after? maybe you are lifting heavier then what is good for your body while on and eq or deca or whatever is helping with the pain. there are tons of maybe's...
if you want to make this a part of your life for years to come you should probably figure out some way that does not depend on staying on lots of drugs no matter what type.
try training lighter and higher reps. address diet, then supps, hrt and a few extra supps should have you feeling great.
