Negative D dimer, please advise?

A D dimer predicts the possibility of a blood clot. I don't know when this was done but if it is more than 2-3 days and you are still having problems with your history I would go to the ER today. As you know a blood clot is not something to be taken lightly. Usually a cklot ill bee in the lower calf felt in te back. If you lay down and keeping your leg on the ground and pull your toes to your head you have a +homans sign, a symptom in clots. Is the back of your leg swollen, warm red? All these can indicate a clot. But with your history and if is a few days I say go o the ER just to be safe! Good luck!
