What is an interlaminar epidural injection? Interlaminar epidural injection is a minimally invasive procedure used to relieve low back pain caused by various conditions such as spinal stenosis, herniated disc, or degenerative disc disease. During the procedure, a small needle is inserted into the epidural space, which is the area between the spinal cord and the outermost layer of the spinal canal, and a steroid medication is injected to reduce inflammation and relieve pain. #epiduralinjection #lowbackpainrelief #backpainrelief #sciaticarelief #sciaticapainrelief #painmanagementphysician #painmanagement #interventionalpainmanagement
