a hard egg-shaped knot came just below my left knee along with swelling surrounding the knot. A few days later, a replica came up on my right leg below the knee. Then a huge place swelled up at my waist on the left side and a few days later a smaller place came up on my right side, with the inside of my body being sore. No more places have come up, but my left leg is sensitive to any sort of pressure--standing too long, sitting too long, walking too long, holding something with weight in my lap, etc. My entire leg becomes sore and hurts. The entire left leg is swollen, including my foot .
