Doctors most commonly use hip joint injections to manage the pain due arthritis or other chronic joint problems, according to Spine-health. They may also use them as a diagnostic tool to help determine whether the joint itself or surrounding tissue is the cause of the pain.
Corticosteroids are the most common type of joint injection, according to InsideRadiology. This steroid, which mimics the naturally produced hormone cortisol, reduces inflammation in the body. Many people experience joint pain due to inflammation in the lining of the joint, so directly injecting steroids into that area can quickly relieve the pain. The injection also typically includes a short-acting local anesthetic to help relieve temporary soreness from the injection itself.
Many patients experience some relief immediately after the injection, according to Spine-health; however, full results may take two to five days. If there is no pain relief after this amount of time, the joint probably was not the cause of the pain, and the patient needs further diagnostics to determine the real source.
There are some potential side effects and risks with hip injections, but the risks are very low, reports InsideRadiology. Some patients experience allergic reactions or may have increased pain due to irritation in the joint. A misplaced injection can result in soft tissue damage, so most doctors use ultrasounds to ensure proper needle placement. There is also a small risk of infection at the injection site, but that is very rare.
