Steroid injections are typically composed of an anesthetic such as lidocaine and/or marcaine as well as the selected steroid. The lidocaine and marcaine take effect almost immediately and can provide relief for several hours. Typically if pain is relieved during this time, then we are addressing the appropriate pain generator. The steroid portion of the injection often takes 2-3 days to begin to take effect.
- Infection – This is an extremely rare, but sometimes severe complications. If you have redness and severe pain following an injection – please seek emergency care.
- Steroid flare – Sometimes patients experience an elevation in pain the day after a steroid injection. This often resolves over the course of 24 hours.
- Elevation in blood glucose – Patients who undergo a steroid injection with a history of diabetes are encouraged to monitor their blood sugar levels and expect an increase over the next three days.
