Quick answer

Corticosteroid injections deliver a powerful anti-inflammatory medication directly to an inflamed joint, tendon sheath, or bursa to reduce pain and swelling. At Wimmer they are placed with image guidance (ultrasound or fluoroscopy) when it adds precision and used judiciously — as targeted relief within a broader plan, not as a reflex for every visit.

What corticosteroid injections do

Corticosteroids are potent anti-inflammatory medications. Injected precisely at the source of inflammation — a joint, bursa, or around a tendon — they can meaningfully reduce pain and swelling, often within days, and open a window for activity, therapy, or the next step in your plan.

When we recommend them

  • Painful arthritis flares interfering with daily life
  • Bursitis and inflammatory soft-tissue pain
  • Conditions where prompt, targeted relief enables progress
  • As a diagnostic aid when the pain source needs confirming

Used judiciously — and honestly

Steroids are a valuable tool, not a long-term strategy. Repeated injections into the same joint are limited for good reason, and we'll tell you candidly when a steroid is the right call, when it isn't, and when a regenerative or maintenance-focused option serves your long-term function better.

Terms to know

An anti-inflammatory medication that may be delivered by injection when clinically appropriate.

Frequently asked questions

How fast do steroid injections work?
Many patients feel relief within days. Duration varies — from weeks to several months — depending on the condition and joint.
How many steroid injections can I have?
Frequency is intentionally limited to protect cartilage and soft tissue. We track timing carefully and discuss alternatives when limits approach.
Steroid shot or PRP — which is right for me?
They do different jobs: steroids calm inflammation quickly; PRP aims to support repair over time. Your diagnosis, goals, and timeline determine the answer, which we cover at your evaluation.
