spondylolisthesis is when one vertebra slips forward over the next. It can reduce the space in the tiny joints where the nerves exit the spine. And produces pain when the medial branch nerve gets pinched on the way out. Your slip is mild.
Stir is an MRI sequence used to better detect edema or nerve damage, especially helpful to reduce "signal noise" when a person has metal implants
Hyperintensity at C5-C6 in the cord and at C4-C5 image either fluid in that space or nerve damage. If the surgery wasn't long ago, it may just be swelling from the procedure. It may be from the disc between the vertebra that disc spaces section indicates is mild/mild to moderate.

There are minimally invasive procedures that can yield relief.
I think it's wise to sort the language before seeing your provider.
