Has anyone had any experiences with blood clots in your legs? My sister has breast cancer and has developed 3 clots within the last month. She had a filter put in which has prevented the clot from moving to her heart. She's been on warfarin for about 2 weeks and was doing great until yesterday when another clot appeared this time in her thigh. Her doctor just said to keep off it and use warm compresses. I would just like feedback on anyone's experience with this. Thanks. kathy
