... diagnosed, spent 4 days in the hospital (my first stay ever) I'm WAY beyond petrified. The clot is in my right thigh and it runs from knee to groin level. They're having a hard time getting the Warfarin level right and I'm just so scared. I don't know what to do. My lower leg is swollen 3 times it's normal size but doctors don't seem concerned about it. Please help with a little advice or even encouragement.
