I was told 1 epidural steroid injection can last a lifetime? true? another doc told me 2 months.

Both: If it cures the underlying problem, 1 injection can last a lifetime. But for chronic problems, it generally will wear off in about a couple of months.

No injection lasts a: Lifetime. Epidural steroid injections can reduce or eliminate inflammatory reaction that is the source of the pain which may or may not recur depending on the initial cause or etiology. For example, most herniated discs get better, so after the injection, your body is healing while the steroid is controlling the inflammation. It is a matter of timing

Varies.: For some people, an esi can calm down the nerves in the spine enough so that pain is alleviated for a long period of time - there is a chance for lifetime relief. Most people find that the relief lasts weeks or months. There is usually some underlying mechanical reason for spine pain.

Not Lifetime Relief: Epidural injections have a variable relief pattern and it really depends on the steroid used and location of pathology. Typically epidural injections work best if placed next to or on top of the level of pathology. Sometimes these injections need to be repeated for sustained relief. Epidural injections if they work can provide from weeks to months of relief. Speak with your doctor re: options.
