I'm new to the board and I have found it to be very informative. I had surgery on Sept. 9th. for L3-L5 and bilateral L3-4 AND L4-5 Foraminotomies. Since the surgery I have real bad pain and stiffness in both knees. Has anyone else experienced severe knee pain after a surgery such as mine? I'm in my second week of PT but it hasn't caused or lessened the pain. I'd be most appreciative for any info that any of you folks have.
