What Causes Hip And Quad Pain After Undergoing Lumbar Laminectomy?

hip and quad pain I just had a lumbar laminectomy and discectomy done 6 weeks ago. I told my neurologist about my quads hurting really bad like an achey cramp. Also, they burn a little along with my hips while they hurt too. The legs feel very heavy and weak. Sometimes I have hard time walking and I stumble a lot with tripping over very small items. My calves are slowly starting to feel the same as my quads. He thinks it is because my lower back muscles were cut. I told him they were like this 6 months to a year prior to the surgery and it feels to be progressively getting worse. They don t feel like this all the time. It usually lasts from one day to two weeks. All he did was just give me muscle relaxers. The reason for the surgery is for eight years I have had degenerative disc disease, bulging discs, herniated disc, sciatica, and spinal stenosis. I am a white 33 year old male and weigh 219 pounds. My question is, what can it be?
