My sister had a petela and ligament reconstruction, plsu numerous other things done because of tears etc. found after going into the knee. Less than one week after surgery and after going to Physical therapy twice she started having a burning sensation on the shin below the knee that was operated on. The knee itself feels pretty good she says, better than it did before the surgery but the morning after the burning sensation started she woek up in severe pain, unable to hold her leg down for any amount of time without severely increasing the pain also it is extremely red. The pain got so bad we had to take her to the emergency room, the first time she went they gave her antibiotics and took cultures looking for some type of blood or skin infection. They took blood her white cell count was normal so they sent her home saying there was nothing they could do till they got the culture results. that same night she was back in the ER due to the pain getting worse and if possible the redness was even more pronounced. they admitted her giving her all kinds of antibiotics intraveniously. They released her the next day, no one can tell us what is causing this and it is not getting better. Does anyone have any suggestions, please we need help!
