Hi livinlife.

I would suggest you see your Primary Care Physician(PCP) and discuss your symptoms and when they happen. Your PCP can do testing as well as refer you to the appropriate specialist if needed.

My first thought was disc herniation(s) and or bulging discs. Your cervical MRI has already shown a herniation and it's possible that you have other disc problems in the Thoracic and /or Lumbar area. These types of problems can cause Neurological symptoms. A spine surgeon/Neuro-surgeon would be the specialist you would need to see for spine problems, not a Neurologist.

Multiple Sclerosis (MS) does not present as you are describing. Movement does not affect symptoms of MS. What is experienced with MS happens regardless if the person is sitting, standing, walking, or laying down.
