Hi
@sandydog I have degeneration in my lower spine, arthritis, with bone on bone and stenosis, picked up on MRI when I had 2 bulging discs. For 99% of the time, I had no back pain, but I had nerve blocks in my lower back last December, due to the pain in my thigh and hip...and knee.
The MRI will show if you too have a bulge in a disc pressing on the sciatic nerve or arthritis etc, as you say, even though you have no pain in your back..
If you do have these problems in your back, they will really know for sure that they do not need to worry that the pain is from your new hip, so will concentrate on your back instead.
In my case, I had another MRI after the back injection, this time of my hips, it showed end stage arthritis hence the bilateral hip replacement.
The spinal surgeon had to discharge from his care, until I got the hips sorted out, as the hip problem was causing very similar pain to the back problem, so they ended up not knowing what was causing the pain in the thigh and hip.
As it turned out, it was both.
I hope that makes sense as I do tend to waffle !
I forgot to say, I am nearly 11 weeks post op and xrays showed nothing wrong with my new hips, but I still had pain in my thigh all the way to the knee and at the side by the new hip. It turned out to be muscle/soft tissue pain, caused by the way the legs are pulled about during surgery and muscle wastage from lack of use. I have just had deep tissue massage and the pain has near enough gone now.
