Just read your post....I have been on coumadin for 25 years due to a MVR in 1986. Now I have to have the valve replaced Feb. 8 due to calcium buildup and an aortic anuerysm repaired. I HATE coumadin...I had 55 protimes last year so over 25 years I have done protimes many, many times. The INR will not stay regulated and I have been on Lovenox injections numberous times. Therefore, I am seriously considering having a tssue valve instead of a mechanical valve this time. I know there is a chance of having to have a "redo" for the tissue valve so really worrying about that situation. Hopefully by the time to redo the tissue valve another option will be available for surgery.
Have a talk to your doctor about things your husband can eat and what he cant eat as it can have an affect with his medications. Hope your husband get better.
Sometimes things change in the body that change what a person needs to take. This doesn't mean anything is wrong. It's just like you can suddenly be allergic to something that never bothered you before in your life. Don't worry about it.
