Corticosteroid injections are one of the most commonly used treatments for pain and inflammation in joints, muscles, tendons, and spine-related conditions. Many people know them as steroid injections, cortisone injections, or anti-inflammatory injections. They are used to reduce swelling, ease pain, and improve movement in conditions such as arthritis, tendonitis, bursitis, back pain, and joint inflammation.
These injections are not painkillers in the usual sense. They work by reducing inflammation at the site of pain. Inflammation is often the main reason for swelling, stiffness, and discomfort in many musculoskeletal and spine conditions. By calming this inflammation, corticosteroid injections can provide significant relief and help patients return to normal activity.
Corticosteroid injections are usually given when other treatments such as rest, medicines, physiotherapy, or lifestyle changes have not given enough relief. They can be used in many parts of the body, including the knee, shoulder, hip, wrist, ankle, spine, and small joints of the hands and feet. In some cases, they are also used for nerve-related pain or inflammation around nerves.
What are Corticosteroid Injections?
Corticosteroid injections are medical injections that contain a man-made form of cortisol, which is a natural hormone produced by the body. Cortisol helps control inflammation, immune response, and stress. When given as an injection, corticosteroids act locally at the site of pain or inflammation.
These injections are different from anabolic steroids used for muscle building. Corticosteroids are anti-inflammatory medicines and are used to reduce swelling and pain. They are commonly used in orthopaedics, rheumatology, pain management, and spine care.
The injection usually contains a corticosteroid medicine along with a local anesthetic. The anesthetic gives quick but short-term relief, while the steroid works over the next few days to reduce inflammation and provide longer-lasting relief.
How do Corticosteroid Injections Work?
Corticosteroid injections work by reducing inflammation at the site of injection.
Mechanism of action
- They suppress the immune response that causes inflammation.
- They reduce swelling in tissues around joints, tendons, or nerves.
- They decrease the production of inflammatory chemicals.
- They help reduce pain by calming irritated nerves and tissues.
- They improve movement by reducing stiffness and swelling.
Why inflammation matters
Inflammation is the body’s natural response to injury or irritation. However, when it becomes chronic or excessive, it can cause pain, swelling, stiffness, and tissue damage. Corticosteroid injections help control this inflammation and give the body a chance to heal.
Types of Corticosteroid Injections
Corticosteroid injections can be classified based on the site of injection and the purpose of treatment.
Based on site of injection
- Joint injections, such as knee, shoulder, hip, ankle, or small joints of hands and feet.
- Tendon or tendon sheath injections, used for tendonitis or tenosynovitis.
- Bursa injections, used for bursitis or inflammation of fluid-filled sacs near joints.
- Spine injections, such as epidural, facet joint, or sacroiliac joint injections.
- Nerve block injections, used for nerve-related pain.
- Soft tissue injections, used for trigger points or muscle pain.
Based on purpose
- Diagnostic injections, used to confirm the source of pain.
- Therapeutic injections, used to treat pain and inflammation.
- Preventive injections, used in some chronic conditions to reduce flare-ups.
