After a Cortisone or Steroid Injection
- Rest the injected area for 24–48 hours. Avoid strenuous activity during this period.
- Mild soreness or a "cortisone flare" — a temporary increase in pain lasting 24–72 hours after the injection — is normal and resolves on its own. Apply ice wrapped in a cloth for 15–20 minutes several times a day to manage discomfort.
- Avoid soaking the injection site for 48 hours (no baths, hot tubs, or pools).
- The full effect of the injection may take 3–7 days to develop. Give it time before assessing whether it helped.
- Diabetic patients: Cortisone injections can temporarily raise blood sugar levels. Monitor your blood sugar more closely over the 24–48 hours following the injection and contact your primary care provider if you have concerns.
