I would recommend pushing for an orthopedic spine specialist to get a lumbar spine MRI and the hip specialist to get you an MRI of your hips/pelvis. You could have soft tissue injury/damage. X-ray alone will not show this.

For example, I have spinal stenosis, degenerative disc disease and neurogenic claudication causing all sorts of symptoms from low back to feet. I also have hip/upper thigh pain that did not show a joint issue with X-ray alone but did show I have bilateral gluteal tendinopathy and bilateral partial high grade hamstring tears (not sure how I got this) that is contributing to pain.

Surgery may be required as a last resort but they should try everything conservative at first (PT, pain relievers, cortisone injections, ice/heat/lidocaine pain patches, nerve pain cream, Voltaren gel for inflammation of joints/muscle tissue, etc.). At times, medication for arthritis/nerve pain/depression due to chronic pain can help (like Cymbalta/duloxetine). A psychologist specializing in chronic pain patients can also help.

Do not stop advocating for your best health and quality of life as possible!
