Neurosurgeon: I presume there was significant, unavoidable nerve tissue injury during the course of spinal surgery. Often slow but partial improvement over many months occurs. Your neurosurgeon is best to answer your question or whether symptoms will be permanent as he/she knows what types of resections were done and what your postop status was on follow-up exams.
