In December, I fell and tore my meniscus. When I fell, I immediately had pain on knee as well as radiating on the outside of my leg, going down to my ankle and up to mid thigh. I went to the ER and they did xray of my knee but didn t address the ankle. It swelled immediately, looked like it had a donut around it. I had surgery on the knee but nothing was done about my ankle. I had problems with my ankle and my calf, muscle pain, knotting up in calf. Finally, it was found that I had torn ligaments in my ankle. I am currently wearing a brace on my left ankle, but week before last, my right foot and ankle started swelling. I am wondering what could be causing this problem. Is it related?
