question: Hi, I had prolonged exposure to carbon monoxide and was hospitalized for three months. During that time I developed dvts in both legs at that time I was given heparin which I had a severe allergic reaction which caused my entire body swell up. They then warfarin which I was on for over ten months. Now Im on a low dose of aspirin. My question is I still clot really fast and my hemotologist doesnt know why. So I would like to possibly know the reason why I clot fast. Thank You
