When you say “my hip started hurting again and I started limping while walking”, is this the same original pain? Where is your “hip pain”? Is it buttocks pain, lateral hip pain (where a 6 shooter would rest in a holster) or groin pain? Was your herniation at L4-5 in the “normal” posterolateral position or far lateral? Did your pain significantly improve after surgery, then get worse? Thigh pain and hip flexor weakness could be from L2 nerve problems but hip disorders commonly cause these symptoms too. Has your hip been checked?
