Hello, Thanks for your query. Based on your description, this is most probably because of a pinched nerve or lower limb radiculopathy (Sciatica). Common cause is bulging intervertebral discs in the vertebral column that compress on the nerves as they come out of the spinal cord - symptoms are experienced along the area of distribution / path of that particular nerve. Here the treatment varies from conservative to surgery. Conservative treatment includes anti-inflammatory medications (pain killers), physical therapy or chiropractic treatment, and avoiding activity that strains the back. Majority of radiculopathy patients respond well to this conservative treatment and symptoms often improve within six weeks to three months. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
