The JANMI Achilles Load Compensation Pattern

Dear reader,

A male client in his mid 50s came to the JANMI clinic with stiffness in both Achilles tendons that had been present for around nine months.

In the last few weeks, he had also started feeling pain around both heel fat pads when waking up, taking the first steps of the day, or walking on stairs. One side was more noticeable than the other.

His history added important context.

He used to run marathons intensively. He is generally hypermobile, had previous issues with one hip feeling as if it was popping out, presented with posterior pelvic tilt, and had prominent bunion changes around the big toe and little toe side on one foot.

From a JANMI perspective, this was not simply an Achilles tendon problem.

The Achilles sits at the meeting point between the calf, heel, foot arch, big toe, knee, hip and pelvis. When the foot loses some of its efficient push off, the calf and Achilles may begin working harder. When the hip and pelvis are less stable, the lower leg may also become more protective.

In a hypermobile body, stiffness can sometimes be the body’s way of creating control. The Achilles may feel tight not only because it lacks flexibility, but because it is trying to create stability during walking, stairs and loading.

The bunion changes also matter. If the big toe and outer foot are not sharing pressure well, the heel and Achilles may receive more repeated strain. Morning heel discomfort and pain on first steps may suggest that the foot and heel tissues are not recovering well between loads.

His marathon history may have built strong endurance, but years of repetitive loading can also leave the body with preferred movement habits. If hip control, foot mechanics and pelvic position change over time, the Achilles may become the area where the old strategy starts to complain.

Pattern 42 of The JANMI Field Guide to 50 Modern Pain Patterns explores how Achilles stiffness, calf dominance, heel loading, foot mechanics, hip stability and pelvic control may influence one another.

The painful tendon matters.

But it may only be one visible part of a much wider loading pattern.

The JANMI Field Guide to 50 Modern Pain Patterns is planned for publication in early August 2026.

This anonymised case is presented for education. JANMI patterns are clinical reasoning frameworks, not medical diagnoses.

Persistent heel pain, swelling, sudden sharp pain, difficulty pushing off, or suspected tendon injury should receive appropriate medical assessment.

Until next time,

Paulius
