Epidurals can cause back pain years later, although this is rare. While epidurals may leave a mother with some soreness at the administration site for a few days or weeks, lasting or recurring back pain is not typical. It may occur, however, because of damage to the spine, nerves, or other structures.The placement of an epidural during labor and delivery requires precision, experience, and training. The anesthesiologist must insert the needle into the epidural space, going just deep enough without penetrating the dura that protects the spine. When something goes wrong during this process, the procedure is in such close proximity to the spine that spinal cord or nerve involvement may be unavoidable.
