I've been playing soccer for a few weeks now but one practice I came home and my legs were killing me. It's been two weeks and it still aches when I go up stairs/down stairs and when I walk in general. OH, especially when I bend my legs, when I try to get in the bed I almost cry when I bend my knee. Right now my legs are throbbing in pain and I can barely get up without excruciating pain. I went to the ER and they said it was overuse, but still I'm really concerned and feel they did a bad job checking me out.
