I agree with Geminigirl that Celebrex might be a good option for you as it is specifically formulated to help with osteoarthritis pain.
Celebrex is COX-2 inhibitor type NSAID
and it is linked to heart attack and stroke. If you have high blood pressure, this medicine may not be the right fit even if it is controlled by blood pressure medications. And over time, NSAIDs increase blood pressure so that is a long term side effect that should be considered.
