I am 42 years old and just had my second back surgery.
ALIF S1-L4 two weeks ago. My back feels pretty good I am happy to say. However Im having some issue with burning behind both knees and if I am standing I can not bend my legs, cant even come clos to getting my leg to a 90 degree angle. Feels like nerve pain, does nto at all feel muscular. Started about 1 week after surgery. Anyone else expreience this?
