What does heel pain feel like with Achilles tendinitis?

The discomfort often follows the Achilles tendon where it joins the heel bone, rather than sitting mainly under the foot. It may be worse when walking uphill, climbing stairs, running, or pushing off the toes. The tendon can feel thick, tender, or warm, and stiffness may be more noticeable after rest or when starting movement.

Heel pain has several possible causes, so its location and triggers are useful details rather than a diagnosis by themselves. A clinician can assess the tendon, ankle movement, strength, footwear, and recent changes in activity.

Reduce or pause the activity that clearly increases pain, while keeping gentle movement within a comfortable range. Supportive footwear and avoiding sudden increases in running, jumping, or hill work may reduce tendon load. Do not begin forceful stretching or strengthening if pain is sharp or symptoms followed an injury; ask a clinician or physiotherapist how to progress safely.

Track whether pain is changing during activity and later that day. This information helps a clinician adjust loading and identify whether the tendon is settling or becoming more irritable.

Seek urgent assessment if you feel a sudden snap or pop, develop marked weakness when pushing off, or cannot walk normally after an injury. Prompt care is also appropriate for rapid swelling, severe pain, or redness and warmth with fever. These signs can indicate a significant tendon injury or another condition needing timely treatment.

Ask whether the pain is centred in the Achilles tendon or another heel structure, which activities are safe, and how to restart strengthening. Clarify what level of discomfort is acceptable during exercises and which changes mean you should stop and return for review.
