I have 9 brain lesions and none on my spine, however I have multiple disc herniations in my cervical spine, yet I have trouble walking. I am really slow and have terrible pain in my feet. I thought you had to have issues with your lumbar space be for this disease to affect walking and cause nerve pain in my feet. Is this incorrect? Can you explain.
Any problem affecting the spinal cord in any location can cause walking problems and abnormal sensation in the feet. Remember, all the fiber tracts passing to and from the lower part of your spinal cord (the region controlling your legs and feet) to the brain must first pass through the entire spinal cord where MS or another process can cause a malfunction in the signals being transmitted that you perceive as weakness and sensory alterations with pain.
A problem in the lower part of your spinal cord (thoracic, lumbar or sacral region) will only affect the legs and leave the arms and hands alone, since the cervical spinal cord (the upper most part of the spine) controls all function in the upper extremities.
Hope this helps.
