Pain in lower extremities. Have anterior iliacsacral rotation. Are there sacral nerves in SI joints that cannot be seen by MRI?

I was symmetrically examined by a highly qualified PT and told me I have right anterior iliacsacral rotation which causes prickling and dull ache this travels down lower extremities and both feet. I had a MRI that only showed broad base diffuse l3-l4 l4-l5-s1 that are not pressing on any nerve roots or thecal sac. Are there sacral nerves in the SI joints that cannot be seen on a MRI?

Thank you for posting your query.

A problem in SI joints can not cause pain radiating down to the feet, as there are no such nerves there travel down to the feet.
However, it is not uncommon for a lumbar or sacral nerve to cause such pains, even if there is no compression seen on the MRI. So, in your case, I feel, your symptoms are related to the lumbar disc prolapse.

Thank you for posting your query.
Your pain in the lower vaginal region and leg pain seems to be neuralgic in nature.
For relief, you may take pregabalin or gabapentin capsules.
Please get back if you require any additional information.
