Eva have they done a neural screen on you? Tendon reflexes, Babinski, Clonus, Hoffman's? Dermatomes? Myotomes? So that you know if upper motor neurons, lower motor neurons, nerve root, or peripheral nerves are involved. The tingling in hands and feet and the weakness tend to be neural issues.

Do you have any issues with numbness in the pelvic floor area? Any problems with bowel and bladder?

If none of the above is an issue, then you're likely looking at postural and musculoskeletal type issues.
