Epidural steroid injections are generally very safe, but there are some rare potential complications. One of the most common risks is for the needle to go too deep and cause a hole in the dura, the tissue that surrounds the spinal cord and nerve roots. When this occurs spinal fluid can leak out through the hole and cause a headache . This headache can be treated with bedrest, or with a blood patch. A blood patch involves drawing some blood from the vein and the injecting it over the hole in the dura. The blood forms a seal over the hole and prevents any further fluid from leaking out.
Some side effects associated with spinal puncture include bruising, bleeding, infections, headaches, and blood clots. Cortisone side effects may cause weight gain, water retention, hot flashes, mood swings or insomnia, and elevated blood sugar levels in people with diabetes. Epidural steroid injections can provide diagnostic and therapeutic benefits. ESIs have been endorsed by the North American Spine Society and the Agency for Healthcare Research and Quality of the Department of Health and Human Services. Discuss this procedure with your friendly and caring doctor at the Florida Spine Institute to determine whether it is the right treatment for you.
