Addiction to cortisone was the subject of the 1956 motion picture, Bigger Than Life , produced by and starring James Mason . Though it was a box-office flop upon its initial release,  many modern critics hail it as a masterpiece and brilliant indictment of contemporary attitudes towards mental illness and addiction.  In 1963, Jean-Luc Godard named it one of the ten best American sound films ever made.  John F. Kennedy needed to regularly use corticosteroids such as cortisone as a treatment for Addison's Disease . 
A small and very rare risk is that the injected joint becomes infected (1 in 15,000). Patients who experience a very painful, red, or swollen joint after injection should seek medical attention immediately. Thankfully, the most common cause of these symptoms is not a concerning infection but a reaction to the injected steroid (called steroid flare ) that occurs in 2-5% of patients. A steroid flare usually begins 6-12 hours after the injection and can last for 2-3 days. Regardless of the cause, it is important for patients with symptoms of infection to see a doctor because infections require immediate treatment.
As mentioned above, there may be more than one spinal structure causing your spine pain. Sometimes, there are multiple causes for your spine pain or radiculopathy. In this case, Dr. Lee may recommend alternative treatment options or steriod injections. For example, if your sciatica/leg pain or hand pain improves with epidural steroid injection but you still have low back pain or neck pain, you may benefit from facet joint injections. But, whatever the case, you will need further evaluation by Dr. Lee to decide on further treatment. Remember that there are multiple treatments available now for pain and just because one method yielded partial or no response DOES NOT necessarily mean you will “just have to live with the pain”!
