Where it hurts decides the structure
Heel pain often sits in an inflamed ligament or tendon. Bottom-of-heel pain usually reads as plantar fasciitis; back-of-heel pain as Achilles tendinitis. First-step pain after rest, swelling, or a shortened stride often travel with that load.
| Where it hurts | Likely structure | Typical tell |
|---|---|---|
| Bottom of the heelUnder the heel pad, toward the arch. | Plantar fascia (plantar fasciitis) | Sharp first steps after rest or sleep; walking may shorten as the day goes on. |
| Back of the heelWhere the tendon meets the heel bone. | Achilles tendon (Achilles tendinitis) | Pain when rising onto the toes, after hills or jumps; the tendon may look puffy. |
