Yes: Yes, that is one of multiple causes. The presence of clonus suggests that you have "spasticity" which is typically associated with some abnormality of the upper motor nerves of the central nervous system; which includes the brain and the cervical and thoracic spine. Thank you for the question.
Dr. Olav Jaren

Clonus: Clonus is a sign that suggests the pathway that regulates muscle contraction was disrupted at some time. It is possible that changes in the brain, not the spine, caused this. But consider this- some people are born this way, and it does not mean that you will eventually be found to have MS. If you had clonus in one ankle, maybe I would think otherwise.

B vitamins: Neuropathy can be very painful but b vitamins can be beneficial in alleviating the pain. You may want to see a neurologist to get further help as far as determining the cause; if you have not done so already.

Caution advised: In the years I have been practicing I have yet to see anyone with significant lasting improvement after radio frequency ablation which is used to cauterize the small nerves supplying sensation to the spine. Assess the risks versus benefits carefully before deciding.
