Steroid injections are a medical treatment that involves injecting corticosteroids directly into an area of the body, often to reduce inflammation and relieve pain. These injections are commonly used for conditions like arthritis, tendonitis, and bursitis. The steroids work by mimicking the effects of hormones produced by the adrenal glands, helping to decrease swelling and improve mobility. The procedure is typically quick and can be done in a doctor's office. While many patients experience relief from their symptoms, potential side effects may include infection, nerve damage, or temporary pain at the injection site. It's important to discuss the risks and benefits with a healthcare provider.
