Hello,
First of all there seems to be multiple problems and with that I mean that I can come up with several diagnosis
1) Vit
b12 deficiency
2) rheumatology coz of inflammatory low back ache
3) gouty arthritis
4) non compressive myelopathy
I'm sure you cannot deduce all of this, so before consulting a super speciality, it's advisable to visit a physician to rule out basic tests first
