Gastric bypass 7 years ago...

I have searched and searched for information about taking NSAIDS after having gastric bypass surgery, and of course all the information I find says do not take NSAIDS after having the surgery... but all those sites are talking about immediately after having the surgery, not 7 years later.

My knees are pretty arthritic, and it would be nice to find something to ease the pain so I can get back to walking without limping.

Anyone know?
