Joint Injections are done for many reasons. For example, if a joint like the knee suddenly becomes swollen, obtaining fluid can help differentiate if it is due to an infection, gout, osteoarthritis or an inflammatory arthritis. It can help control pain and swelling in the joint by administering medications directly into the area.  This helps particularly in people with an inflammatory arthritis like rheumatoid arthritis where joints can “flare-up”, even as they take their systemic therapy. Your doctor can refer you for an injection at any point these indications are met, and we’d like to walk you through the process.
