Corticosteroid injections are a medical treatment used to reduce inflammation and relieve pain in various conditions, such as arthritis, tendonitis, and bursitis. These injections deliver a concentrated dose of corticosteroids, which are synthetic drugs that mimic the effects of hormones produced by the adrenal glands. The injections can provide quick relief and are often used when other treatments, like oral medications or physical therapy, have not been effective. The procedure typically involves a healthcare professional injecting the corticosteroid directly into the affected area, such as a joint or soft tissue. While many patients experience significant pain relief, the effects can vary, and repeated injections may be necessary. However, there are limits to how often these injections can be given, as excessive use may lead to side effects, including joint damage or weakened tissues.
