I had a L5-S1 ALIF about 5 weeks ago. I had the surgery to relieve extreme right sided pain. I couldn't stand or walk for any distance without great discomfort. Post surgery the pain on the right side is almost completely gone. I am now able to walk 2 to 4 miles a day without any pain. However, in the last three weeks I have developed a great deal of pain in my left hip. The pain has now drifted to my lower left leg and top of my foot. It feels like my the area below my knee is in a visegrip. It wakes me up in the middle of the night and I can't get back to sleep without taking the narcotic that was prescribed by my MD after surgery. The MD has prescribed lyrica and that has provided no relief. Basically my lower left leg throbs all day long but oddly does not prohibit me from walking. Has anyone had such symptoms. Can anyone offer any hope. Thanks for your consideration to all.
