This is a guess as a therapist about calf pain.
There is a high possibility that the range of motion of flexion and extension of the hip joint is narrow.
・Mechanism of the body
In order of muscle strength: hip joint → knee joint → ankle joint
Easy-to-use order: Ankle joint → Knee joint → Hip joint
Why do calves hurt?
The hip joint has large muscles and produces a large amount of force, but it also consumes a large amount of energy.
Therefore, there is a possibility that the calf of the ankle joint, which consumes less energy, is overused.
① Stretching to expand the range of motion of the hip joint
②Be aware of using the hip joint every day
③Stretching from toes to soles and calves
