A corticosteroid injection can be an effective treatment for meralgia paresthetica when conservative measures fail to control symptoms. The injection is typically placed near the lateral femoral cutaneous nerve, often under ultrasound guidance, to reduce local inflammation and nerve irritation. Many patients experience partial or complete pain relief, which may last weeks to months, though symptoms can recur. This approach is mainly used for significant pain rather than numbness alone. Risks are generally low but can include temporary discomfort, skin changes, or infection at the injection site.
