What should you know about tailbone pain and psoriatic arthritis?

Psoriatic arthritis is an inflammatory joint condition associated with psoriasis in some people. Inflammation near the pelvis or spine may cause deep buttock or tailbone-area discomfort, reduced movement, and stiffness after rest. A flare can also involve [Joint Pain](/symptoms/joint-pain/), [Joint Swelling](/symptoms/joint-swelling/), or [Morning Joint Stiffness](/symptoms/morning-joint-stiffness/). Tailbone pain has other possible causes, including injury and local irritation, so location alone cannot establish the diagnosis.

Record when pain starts, how long morning stiffness lasts, skin or nail changes, and any swollen joints. Gentle movement and a personalised exercise plan can protect mobility; [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) may help with posture, strength, and pacing. A clinician may discuss [Anti-Inflammatory Medication](/treatments/non-surgical-orthopedics/anti-inflammatory-medication/) or other disease-directed treatment. Take prescribed treatment as directed and avoid changing it without medical advice.

Book an appointment if tailbone-area pain persists, repeatedly disrupts sleep, or appears with prolonged stiffness, swollen joints, or a psoriasis flare. Seek urgent care for new leg weakness, numbness around the groin, loss of bladder or bowel control, fever with a hot swollen joint, or severe pain after an injury.

Ask whether the pain pattern suggests inflammation near the pelvis, what examination or imaging may clarify the cause, and how skin, nail, eye, or bowel symptoms affect treatment choices. Ask how to pace activity during a flare and when follow-up is needed.
