How Long Does a Cortisone Injection Take to Work for Hip Osteoarthritis?

A local anaesthetic may provide short-lived numbness or relief soon after the injection. Once that wears off, the hip can feel as it did before until the corticosteroid's anti-inflammatory action develops. Osteoarthritis involves changes inside the joint, including irritation that can flare with walking, stairs, or prolonged standing. An injection can calm inflammation and make movement more comfortable, but it does not rebuild cartilage or reverse joint changes. A response can help show how much pain is coming from the hip joint, yet it is only one part of treatment planning.

Use the post-procedure instructions from your clinician. Protect the hip from heavy loading during the advised early period, then increase walking and other activities step by step. Do not treat temporary relief as permission to suddenly resume every painful activity. Gentle strengthening and mobility work, often guided by physiotherapy, can help maintain function while the hip is more comfortable. Note pain at rest, during walking, and at night, along with any change in your daily activities. This record gives your clinician useful information at follow-up.

Get in touch with the treating service if pain is steadily worsening, the skin is hot or increasingly swollen, or you develop fever or feel unwell. Seek urgent care for severe pain with inability to bear weight, new weakness, or loss of bladder or bowel control. If the injection has not helped by the review point your clinician gave you, book an assessment to discuss other options instead of arranging repeat treatment without advice.

Ask how long to limit weight-bearing activity, when physiotherapy can restart, and what improvement would count as a useful response. Ask what alternatives are suitable if pain returns, and whether your other medicines or health conditions affect injection planning.
