Hi
I think you are being guided by broad brush stroke and not having careful thought put into your management.

Q. Should Celebrex be avoided in patients receiving warfarin or similar products?
A. Patients receiving warfarin can also receive Celebrex. Since Celebrex by itself does not affect platelet function or bleeding time, it can be an appropriate treatment option for patients taking warfarin, as long as the anticoagulation effect of warfarin is maintained at the proper level. To minimize any increased risk of bleeding, patients should be closely monitored (especially in the first few days) to see if any adjustment of their warfarin dosing is needed.
Q. What does this mean regarding the overall safety of Celebrex?
A. Patients receiving warfarin require monitoring of the level of anticoagulation produced by that drug. It is not unusual for them to need a change in warfarin dosage when there are changes in the other medicines they are receiving. Celebrex does not pose a unique or special risk in this regard, compared to other medicines that patients may receive. It is important, however, that patients who are receiving warfarin and then start taking Celebrex (or who have any other change in the other medicines that they are taking) be monitored for changes in the level of their anticoagulation, with adjustments in the dose of warfarin if necessary.
This is what all of us who self monitor do, check closely. Also this is why he establishments in the US get poor results (still) by persisting with outdated policy of not fostering self testing in capable patients.
Sadly your story of pushed towards tissue prosthetic when younger and then getting less than 15 years is quite common here.
You have but a few days to make your call, but raise that information with your team and become informed as to the specific issues relating to you ... One size does not fit all
Some food for thought
