Am I right to be wanting another opinion?

[steph43064]

Last year I was diagnosed with Spondylolisthesis and degenerative disc disease. 9 days later, I started realising that there were changes to the sensation in my saddle area. Woke up next morning and had wet myself, lost all sensation in saddle area and relatives took me to a&e to be told to wait for scan in 3 days.

MRI came back with this report
L3/L4 - there is no significant disc protrusion or evidence of neural compression
L4/L5 - there is a broad based protrusion but no significant lateral recess narrowing or evidence of neural compression
L5/S1 - there is spondylolisthesis with bilateral pars defect, marked bilateral exit foraminal narrowing and compression of the exiting left L5 nerve root and possibly the right. There is narrowing of the lateral recesses.

This was the first and only MRI scan I had on that area of my spine so not sure how much has changed in the last 19 months.

Within 3 months I'd lost all feeling in legs, had no bladder or bowel control of which I found out in the August I'd actually had urinary retention with overflow incontinence for god knows how long and was relying on a wheelchair to get about. The neurologist I had been referred to said straight away that it was conversion disorder and that my spinal problem would not be the cause of these symptoms. The urology nurse who helps me with my bladder has told me she absolutely thinks it's CES, 2 GPs also think it's CES, a physio who I was referred to said that there's no way I have conversion disorder, and a doctor who I saw when in hospital said if it is CES that I have no hope of recovering because they've missed the opportunity to operate but that I should just continue to be treated for conversion disorder in case it is that and not my spine (I have continued with the treatment although I think it's a waste of time because I'm quite frankly not improving and getting nowhere).

So should I fight to get another opinion in case it is CES and then attempt to get the conversion disorder diagnosis overturned or should I accept that it definitely is conversion disorder.
