Hi, My husband has had his left foot, toes, and ankle swollen for 10 days. It doesn t hurt. We went to the ER and they checked for blood clot and fracture. Both were negative. They told us because it was only one foot it wasn t his water retention as he was taking his water pill. It doesn t hurt to touch. It slightly goes down with ice and elevation. We ve tried ibuprofen, ice, elevation, soaking in epsom salt all with little improvement. Tonight we inspected it and found yellow spots with red on the bottom of his foot under his toes. What should we do?
