In patients with systemic lupus erythematosus, most suffer from arthralgia. The joint pain caused by systemic lupus erythematosus is due to the deposition of immune complexes in the joint cavity, or inflammation of the blood vessels nourishing the joints. This primarily manifests as joint swelling and pain, and often occurs symmetrically. When joint pain occurs in lupus, in addition to corticosteroid therapy, we can also use non-steroidal anti-inflammatory drugs (NSAIDs) under the guidance of a doctor. These drugs can achieve good analgesic and anti-inflammatory effects. However, patients with renal insufficiency should use these drugs with caution.
