How effective is cortisone injection for heel spur?

A cortisone injection may temporarily ease inflammation-related heel pain, but it does not dissolve a heel spur or correct the reason the area became overloaded. The spur seen on an image may not be the only pain source, so treatment should follow an examination rather than the scan alone. Exercise, footwear, and load changes often remain central to recovery.

A heel spur is a bony growth near the heel. Pain may instead involve irritated soft tissue under the foot or around the heel, and the location of tenderness matters. Cortisone can calm local inflammation, which may make walking more comfortable for a time. It cannot remove bone, restore tissue capacity, or guarantee that pain will stay away. A clinician may consider other causes if symptoms do not match the expected pattern.

Wear supportive footwear and avoid sudden increases in standing, running, or jumping while the heel settles. Your physiotherapist may prescribe calf and foot exercises, then progress them as tolerance improves. Ask how soon to resume normal activity after an injection and follow the agreed plan. Note morning pain, walking distance, and the activities that trigger symptoms; this helps guide the next step.

Contact the clinic if the injection site becomes hot, red, increasingly swollen, or very painful, especially with fever or feeling unwell. Seek urgent assessment for sudden inability to bear weight, a new injury, severe bruising, or a cold or numb foot. Arrange review if heel pain persists, changes location, or prevents ordinary walking despite treatment.

Ask what structure is thought to be painful, whether the spur is relevant to your symptoms, and what exercise or footwear changes should accompany the injection. Clarify aftercare, warning signs, alternatives, and when persistent pain would require imaging or another diagnosis to be considered.
