Glad to hear she's back home. Blood clots can be very serious, but the drugs are effective. Both my mom and dad took drugs for that after a couple of incidents. Mom's was clots in her lungs, too. She may have to stay on it forever, but her doctor will check her blood work on a regular basis. It's very important that she doesn't miss her drug. The only time mom didn't take hers was when she fell and hit her head and that was only for a few days. Still praying here.
