Psoriatic Arthritis in the Heel

The Achilles tendon attaches at the back of the heel, while the plantar fascia attaches underneath it. Psoriatic arthritis may inflame these attachment areas, a process called enthesitis. Pain can be worse with the first steps after rest, after prolonged standing, or when pressure is placed on the heel. Heel pain also occurs with footwear problems, injury, or other conditions, so it should not be self-diagnosed.

Choose supportive, well-fitting shoes and avoid walking barefoot on hard surfaces if that aggravates symptoms. Reduce impact temporarily, but keep gentle ankle movement within comfort. A physiotherapist can guide calf, foot, and lower-limb exercises and check walking mechanics. Your clinician may discuss anti-inflammatory medication or other treatment depending on the whole pattern of arthritis. Do not push through increasing swelling or sharp pain.

Arrange an appointment when heel pain lasts, limits walking, or occurs with swollen joints, morning stiffness, or psoriasis. Seek prompt help if the heel becomes markedly red and hot, pain begins suddenly after an injury, or you cannot bear weight. Fever with a severely painful swollen area needs urgent assessment.

Ask whether the pain is coming from the Achilles attachment, the underside of the heel, or another structure. Discuss footwear, exercise progression, medication options, and whether physiotherapy or imaging would clarify the cause.
