Lumbar Transforaminal Epidural Steroid Injection is carried out to remove pain in the lower part of the back as well as pain radiating down the leg. Steroid medication reduces swelling and inflammation, caused by spinal channel narrowing, radiculopathy, sciatica and vertebral disk protrusion. In some cases it is necessary to repeat Lumbar Transforaminal Epidural Steroid Injection up to three times to get a maximal effect from the medication; however, most of the patients get a substantial pain relief after one or two injections. During this Lumbar Transforaminal Epidural Steroid Injection patient lies face down with a soft pad under the stomach for a better comfort and to help to relax the spine. Such position of a spine gives an easy access to the epidural cavity. A fluoroscope helps to find the specific lumbar vertebrae and nervous routs. In the site of injection a local anesthetic is used first, which numbs all tissues up to the surface of the vertebra. Using fluoroscope the doctor introduces a thin bent needle in the foraminal space near nerve ending. Contrast substance helps to verify the correct position of the needle. Then into the foraminal epidural cavity a steroid-anesthetic mixture is introduced, which soothes the painful nerve ending. After the needle removal a small band-aid covers the place of injection. Possible side-effects are comparable with side-effects of a simple injection: patient may have allergic reactions, bacterial infection or bleeding, which occurs rarely.Steroid side-effects: swelling of the face, arms and legs, diabetics may have their blood sugar level raised. It is obligatory to inform your physician about pregnancy or the use of ‘blood thinning’ medications.
