Abductor Hallucis overload and Flexor Hallucis Longus stiffness in the 10K weekend runner

Dear reader,

If your bunion side aches and the big toe feels stiff after a 10K, your foot is telling a bigger story than a sore bump.

The usual local suspects are the abductor hallucis along the inner arch, the flexor hallucis longus tendon line behind the medial ankle, and the soft tissues around the first metatarsophalangeal joint and sesamoids.

When these tissues get overloaded, the big toe stops bending smoothly during push off. Then the foot loses its clean lever and starts borrowing movement from elsewhere.

This is where the JANMI chain logic becomes useful. A stiff big toe often means the arch cannot stiffen at the right time. The midfoot collapses earlier, the tibia tends to rotate in for longer, the knee follows, and the hip and pelvis have to stabilise harder to keep you moving forward. The pain shows up at the bunion side, but the pattern usually involves foot, knee, hip, pelvis, ribcage, and scapula load sharing.

In a JANMI Full Chain Reset at JANMI Postural Pain Clinic Marylebone, I look at first MTP joint glide, sesamoid area tension, and the tone of abductor hallucis, flexor hallucis brevis, and adductor hallucis. I also trace the flexor hallucis longus pathway through calf and ankle, because a tight cable there can make the toe feel blocked. Then I check how the knee and hip control rotation, because your big toe should not have to act as the main stability plan for the whole body.

If your toe stiffness is making you roll to the outside of the foot or feel awkward on push off, it is often not weakness or age. It is mechanics, tissue capacity, and chain compensation. The good news is that mechanics can be changed when you treat the pattern rather than just the painful spot.
