Thanks for pointing out that anyone on drugs such as Coumaden (warfarin) for the prevention of blood clots should definitely check first with their doctor. It may be clearly contradindicated in their situation. I certainly should have added that to my discussion. As for my second post those were the classifications from who ever it was that viewd her previous bone scan and wrote up the report. I know this can vary and may be misleading, which is why in my first post I added that my improvement had reached the level of being considered clinically significant.
