A cortisone injection involves delivering a corticosteroid medication directly into a specific area of the foot. This medication works to reduce inflammation, which is often the underlying cause of pain in conditions like arthritis, plantar fasciitis, or tendonitis. Many people wonder about the need for rest after this procedure to facilitate healing and maximize its effectiveness.
Immediate Post-Injection Recommendations
Following a cortisone injection in the foot, immediate rest for the first 24 to 48 hours is recommended to allow the medication to settle in the targeted area. This initial period of reduced activity helps prevent the corticosteroid from dispersing too quickly, allowing it to begin its anti-inflammatory action. While the injection itself may contain a local anesthetic for immediate pain relief, the corticosteroid takes a few days to fully take effect.
Applying ice to the injection site can help manage swelling or discomfort after the procedure. Using an ice pack for 15-20 minutes at a time, several times a day, can provide relief. Elevating the foot also reduces swelling by promoting fluid drainage. Avoiding strenuous activities, prolonged standing, or heavy weight-bearing minimizes irritation and supports early recovery.
Activity Guidelines and Recovery Timeline
After the initial 24 to 48 hours of immediate rest, a gradual return to activity is advised, rather than an abrupt resumption of normal routines. High-impact activities such as running, jumping, or intense sports should be avoided for at least a few days to a week, or longer depending on the condition. Activities involving prolonged standing or repetitive stress on the foot should also be limited during early recovery.
The exact timeline for resuming full activity varies based on the individual’s condition, the severity of the inflammation, and the injection site. While some may feel relief within hours or days, full benefits often appear within one to three weeks. Healthcare providers provide personalized guidance on activity restrictions and a gradual return to normal routines.
What to Watch For
While cortisone injections are considered safe and effective, be aware of potential reactions or complications. A common, temporary side effect is a “cortisone flare,” a temporary increase in pain at the injection site for 24 to 48 hours. This occurs as cortisone crystallizes in the tissue before dissolving and reducing inflammation.
Less common, but more serious, signs of infection include:
Increased redness
Warmth
Significant swelling
Pus at the injection site
Fever
If any of these symptoms appear, or if pain significantly worsens or new symptoms develop after the initial post-injection period, contact a healthcare provider promptly for evaluation.
