my surgeon's office said 10 days pre-op to be off coumadin, so my surgery is 2/10/11, and i will stop taking it today, and will start the Lovenox injections all the way up until the day of surgery. then, the day after surgery i start the Lovenox shots again, and also the coumadin, and will go from there.
