Overview
Joint injections are shots into a joint, such as the knee. They may be used to put in medicines, such as pain relievers.
A corticosteroid, or steroid, shot is used to reduce inflammation in tendons or joints. It is often used to treat problems such as arthritis, tendinitis, and bursitis.
Steroids can be injected directly into a painful, inflamed joint. They can also help reduce inflammation of a bursa. A bursa is a sac of fluid. It cushions and lubricates areas where tendons, ligaments, skin, muscles, or bones rub against each other.
A steroid shot can sometimes help with short-term pain relief when other treatments haven't worked. If steroid shots help, pain may improve for weeks or months.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
