Why would one foot remain swollen after Vein Ablation surgery ?

I had Vein Ablation surgery two weeks ago and am healing with couple of problems. My incision sites are numb and tingling at times. My left foot is also incredibly swollen and painful. It hurts to moves my toes and foot in the slightest bit. My thighs feel tight like a rubber band and hurts to move.

I had my ultrasound performed and was cleared for blood clots I wear compression socks everyday to work and elevate at home on a wedge to help. I am also on two different water pills even before the procedure.
