Scoliosis and lower stomach pain

[Spursboy]

I have been diagnosed with scoliosis which means I have pain in my lower back, down right leg plus both feet have pins & needles.

I have had various injection, pain killers and last December Lumbar decompression surgery non of which has helped, still painful when I walk or stand.

The last couple of months I seem to be getting pain in my lower stomach area and wonder if the two things are associated?

I have also had physical therapy, acupuncture and at present seeing an Osteopath [3visits] but no improvement to date.

Waiting to got to NHS pain clinic but it's a long waiting list and will not be until March/April.

Any suggestions please
