Spinal (Back & Neck) Injections
What is an injection?

This is usually used to help relieve back or muscle pain caused by arthritis, strain or impingement a nerve. In conjunction with your referring Doctor, the performing Radiologist will consider your clinical symptoms to determine the type and location to administer the injection.
