I believe I have a blood clot on the top of my right foot. I have a Doppler scheduled Tuesday but I believe it's getting worse. It really hurts,is warm to the touch & swollen. It's becoming dark colored like a bruise. I have a blood clotting disorder called antiphospholipid antibody. In the past,I've had several clots in superficial veins & 1 dvt. I'm on plavix & aspirin. My question is this. Shld I wait til my appointment tues or go 2 the er?
