Hi.One of the commonest reasons for leg pain(Sciatica
) is due to the pressure of one of the nerves coming out from our spinal canal(junction of lumbar and sacral spine).Soft tissue(disc) is present between two consecutive bones in the spinal canal which will act like a shock absorber. Due to aging or injury
this tissue protrudes and compresses the adjacent nerve which causes neurological symptoms like pain, tingling numbness
in the area of the body where it supplies.Depending on the intensity this can be managed by conservative treatment(braces) , pain revealing medication and surgery if it is severe.Discuss with Orthopedist for further management.Hope this helps.Take care.
