Even in a small joint, osteoarthritis (OA) can have a big impact on your life. For instance, OA in your fingers can keep you from holding a pen or opening a jar. A stiff or sore knee can make it hard to walk.
Getting a shot of corticosteroids (sometimes called a steroid shot) directly into a sore joint can ease pain quickly.
Creaky, achy joints. A twinge in the knee. A sharp shooting pain from the shoulder to the elbow. No big deal, right?
Wrong. All too often, we assume joint pain is a normal part of aging that we just have to learn to live with. Nothing could be further from the truth, say experts, pointing to a wealth of treatment options from exercise and alternative supplements to medications and joint replacement surgery.
It's a serious problem, because pain can affect every aspect of your life. "Pain is not...
Corticosteroids help fight inflammation -- the heat, redness, pain, and swelling in an injured or inflamed part of the body. Corticosteroid shots ease pain faster than anti-inflammatory pills. A single injection doesn’t cause stomach upset the way pills can. When corticosteroids are injected into a joint, their effects are mostly limited to that joint.
What to Expect
Most corticosteroid injections into your knee or a smaller joint, like the base of your thumb, can be done in a doctor’s office.
First, the doctor cleans your skin with an antiseptic. If the joint is puffy and filled with fluid, the doctor may insert a needle into the joint to remove the excess fluid. This quickly relieves some of the pain, because it reduces pressure in the joint. Removing extra fluid may also speed healing.
Next, the doctor uses a different syringe to inject the corticosteroid into the joint. Relief is almost instant, because the corticosteroid is usually mixed with a painkiller. The corticosteroid begins to curb inflammation within a few hours. The relief usually lasts from several weeks to several months.
Injecting a large joint, such as your hip, or in the spine is more complex. Your doctor may use imaging technology to help guide the needle into place.
