question: I had a knee arthroscopy 16 days ago. About 4 days post-op, I developed severe swelling, from mid-thigh to ankle. They drained my knee at 7 days and prescribed TED hose, as I had to drive in the car for 8 hours later that day. The swelling has subsided, but I have had extreme calf pain for 4 days. No redness or swelling, though. It is worse when I have been sitting or lying down and get up, I almost collapse. It seems to get better as I walk around throughout the day, but worsens again if I sit down and try to get back up. Is this just from walking differently on my leg? I feel like I ran a marathon in a pair of high heels (but only on the leg I had surgery on.)
