Brief Answer: nerve related pain Detailed Answer: HI, thanks for using healthcare magic Electric shock sensations or other abnormal sensations are usually related to abnormal function or structure of one or more nerves. The nerves that supply the lower limbs originate from the spine and any abnormal sensation related to these nerves can be due to any abnormality in the back or as the nerves pass through different aspects of the legs. There are different possible causes for the feeling you had: (1) there could be a mass compressing the nerve -for example arthritis in the spine or hips may affect the nerves coming out in those areas (2)vitamin deficiency affecting nerve function- b1, b12, b6 (3)diabetes (4)trauma to a nerve (5)alcohol use (6)liver or kidney disease If it persists your doctor can determine the nerve that is likely involved by history and examination. If the specific cause can be determined then it can be treated appropriately. There are pain killers that can specifically treat nerve related pain. I hope this helps, feel free to ask any additional questions
