thanks for posting,
You are likely experience a temporary or transient peripheral neuropathy
which might not be direct medical condition in which you can worry about. How ever, it is better you consult a neurologist
and get your blood sugar tested and blood pressure measured to rule out causes due to diabetes
respectively. Other possible causes of the neuropathy might be involved.
But to me, it is nothing to worry about, it might just be some spikes of electric flow, that provoke a headache.
hope this helps
