Heel pain when hooking the toes may be caused by physiological factors such as long-term strain and cold stimulation, or it may be caused by pathological reasons such as abnormal arches and lumbar intervertebral disc herniation. 1. Physiological factors: long-term strain on the heel area will lead to micro-injury of the Achilles tendon attachment site and aseptic inflammation, which may induce heel pain when hooking the toes, such as Achilles tendon attachment point inflammation, Achilles tendonitis, etc.; prolonged exposure to a cold and humid environment will lead to the contraction of small blood vessels in the heel area and shortening of the Achilles tendon, and the Achilles tendon will be overstretched when hooking the toes, which may induce pain. 2. Pathological factors: congenital or acquired abnormalities of the arch structure may also lead to excessive tension on the Achilles tendon when hooking the toes, causing pain symptoms, such as flat feet, etc. In addition, when the nerves that innervate the heel area are compressed, heel pain when hooking the toes may occur, such as lumbar intervertebral disc protrusion, lumbar vertebral spondylolisthesis, and pyriformis syndrome. The symptoms of heel pain sometimes can not accurately determine the cause, but also need to be combined with the characteristics of the medical history, other test results in order to make an accurate judgment, it is recommended to clarify the cause of the disease under the guidance of a doctor.
