How long does a cortisone injection take to work for coccydynia?

Cortisone is intended to calm inflammation near the coccyx. Sitting puts direct pressure on this area, so that activity may remain uncomfortable even as background pain improves. A local anaesthetic may provide earlier, shorter relief. The injection cannot correct every possible cause of tailbone pain, such as an injury, pelvic floor tension, or another nearby problem, so the response helps guide follow-up.

Change position regularly and use the cushion or sitting technique recommended by your clinician. Avoid activities that sharply increase pressure on the tailbone while the injection settles. Record pain while sitting, standing, and moving, rather than judging the result from one moment. Follow prescribed exercises carefully and ask before restarting activities that caused the original flare. Details about the procedure are available in [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/).

Seek prompt advice for increasing redness, swelling, drainage, severe pain, fever, or feeling unwell after the injection. Get urgent help for breathing difficulty, facial swelling, or widespread hives. Contact your clinician if new leg weakness, loss of bladder or bowel control, or numbness around the saddle area develops.

Ask what sitting position is safest, when to begin pelvic or core exercises, and how long to wait before reviewing ongoing pain.
