Hi I am wondering if anyone else is having this problem. I had a tlif for l4/l5 2 weeks ago. Over the last couple days my right lower leg has been swollen and painful. They did an ultrasound to rule out a blood clot. It was negative and now the doctor says he doens't know what it could be. My leg is so achy and sore. I am at a loss as to what it could be. It is honestly more painful than my back right now. Any suggestions?
