A 22-year-old male presents with posterior heel pain after starting a new job that requires a lot of walking. His skin over the heel is red. The skin is intact.  There is no swelling or “pump bump”.



The following images of the Achilles tendon were obtained in long and short axis.

Achilles tendon in long axis
