Epidural Steroid Injections


Epidural Steroid Injection (ESI) is an non-surgical treatment that may alleviate neck/back and arm/leg pain caused by conditions such as spinal stenosis, disc herniation and degenerative disc disease.

Medicines are delivered into the epidural space which lies between the protective covering of the spinal cord (dura mater) and the bony vertebral wall.

The goal is to reduce pain by diminishing inflammation of the spinal nerves so you may improve your daily function and continue with your rehabilitative exercises.


After an initial consultation with Dr. Chowdhury and your questions answered satisfactorily, you will be escorted to a procedure suite and positioned prone on the fluoroscopic table. The target site is cleansed with antiseptic solution and sterilely draped. The skin over the injection site is numbed with a local anesthetic. A thin needle is then inserted into the epidural space under X-ray guidance. Once needle placement is confirmed, depomedrol is injected into the epidural space. The whole process takes approximately 15-20 minutes, with the actual procedure only taking 2-3 minutes.

Post Procedure:

Most patients are able to leave the clinic upon completion of the procedure. Avoid strenuous activities over the next 24 to 48 hours. Application of ice and oral intake of mild analgesics usually will alleviate potential soreness over the injection site although flair-ups are possible. Potential side effects from steroid administration may include transient flushing, restlessness and elevation of blood sugar. You should follow up with your referring physician’s office in 10 to 14 days and report overall treatment response. There are no consensus in the medical community regarding the frequency of epidural steroid injections, the most prudent recommendation suggests evaluation of each and every injection prior to further treatments are planned.
