A joint injection is a procedure used to treat inflammatory joint conditions, such as psoriatic arthritis, tendinitis, bursitis, Carpal Tunnel Syndrome, rheumatoid arthritis and sometimes osteoarthritis.
A hypodermic needle is used to inject the affected joint(s), where it inserts a dose of an anti-inflammatory agent. Some of the most common agents are Hyaluronic acid, Corticosteroids, and Viscosity is sometimes used to replace the bursa fluids in your body. The same technique can be used to extract excess fluids from the joints.
The insertion of an anti-inflammatory agent helps reduce inflammation and/or swelling of tissue in a joint space. Results vary, but it should help reduce pain, and other symptoms that are caused by the inflammation and irritation of the joint and surrounding areas.
This procedure is rather painless, but the results should be almost instantaneously. After the joint injection, the pain you are experiencing should be gone or quite less. This effect will only last for a couple of hours, and your pain will return eventually. You may even experience a sore joint due to the process of inserting the needle. In about 3 to 5 days, you should start noticing pain relief.
Joint injections prove to be beneficial, but they are not a lifetime guarantee. Each injection can last from 2 to 3 weeks or even a couple of months. Patients who are experiencing milder pain in their joints tend to respond much better than patients who experience severe pain.
