I fell 6 days ago, bruising my right leg, below the knee. Moderate swelling with bruising and redness on front of leg. Today, I have intense burning when I first get up from sitting and start walking. It eases up after a while. Flexing my foot also seems to agitate, but lessens as I relax my foot. What have I done? I am also a diabetic (type 2), and taking Plavix for perifial artery disease in my head.
