Why does the joint cavity hurt after receiving a sodium hyaluronate injection, and what should be done?
Pain following sodium hyaluronate injection into the joint cavity may be related to drug irritation, improper procedure, bacterial infection, or other causes. It can be managed through daily care and medication. Specific analyses are as follows:
1. Drug irritation
Injecting sodium hyaluronate into the joint cavity is a treatment for osteoarthritis that helps reduce inflammation and joint pain while improving joint function. If the sodium hyaluronate irritates the joint tissues, it may cause pain. This condition does not require special treatment and typically resolves once the drug has been metabolized.
2. Improper procedure
If the needle fails to accurately enter the joint during injection, it may damage blood vessels around the joint, leading to intra-articular bleeding and subsequent pain. Patients may take medications such as diclofenac sodium sustained-release tablets or ibuprofen sustained-release tablets as directed by a physician to relieve symptoms.
3. Bacterial infection
If strict disinfection protocols are not followed during injection, it may result in joint infection, causing pain and inflammation. In such cases, patients may be prescribed antibiotic medications like levofloxacin hydrochloride tablets or amoxicillin capsules, to be taken under medical guidance.
In addition to the common causes mentioned above, pain may also be associated with allergic reactions or excessive joint effusion. Patients should seek medical evaluation at a hospital to determine the underlying cause and receive standardized management or treatment.
