My 16 daughter had ACL surgery 9 days ago and has been complaing about foot pain. The top of her foot is numb but she is complaining of pain inside her foot and sometimes her calf. She gets some relief when she ices and elevates but when she stands the pain is back and doesn't go away. We had to do a round of IV antibiotics because her knee was swollen, red and very warm after her first visit to physical therapy. Please tell me if anyone has experienced this and knows what it is. Thanks so much.
