I fell very hard on my left knee three weeks ago today. Have been seen twice and xray d, no breaks. Swelling and bruising in knee has gone down, but still painful and pops on occasion. What has me concerned is the pooling of blood down my shin , into my instep. Most has cleared up, but I m still getting blue new discoloration. Last night my whole ankle and foot was grossly swollen, red, and hot to the touch. It seems better this morning. Should I be concerened? I am 5 170 lbs, 56 years old. I ve been icing and taking naproxen . neither seem to help much.
