I had DVT in my left leg, it seemed to be at the top close to my crotch, next morning my left leg was twice the size of my right one. Went to ER right away and had a Doppler ultrasound and the entire main artery was plugged with a big clot. I was on Warfarin for six months to dissolve it. My blood created new pathways to my foot and back, I now have bulging secondary arterials close to the skin, not too pretty, and my left foot and ankle remains purplish and splotchy. Got that from self medicating earlier, now I'm on a low dose patch only as topical is much safer.
