Sorry to hear about the health condition. Plumbstraight is currently in a similar situation with blood thinners. I wouldn't ride in this case until off the blood thinners. Sometimes giving into the pain puts you in worse condition. If you feel good enough to ride I would keep doing so but just find a buddy to take along and make them aware of your health condition. The riding is good exercise and you don't have to go fast to have fun. This would ease your wife's concern. She might ride a Tdub, let her try. You could buy another, take it slow and enjoy them together.
