Calcaneal tuberosity

Looks like

The rounded back and underside of the heel bone.

What it does

The Achilles tendon ends on its back; the plantar fascia and short foot muscles start from its underside.

Keeping it well

Pain where the Achilles meets it, or under the heel on the first steps of the day (plantar heel pain), usually settles with calf loading exercises and time.
