Patients with painful walking on the soles of their feet when they wake up in the morning, but the pain disappears after a while, are seen with plantar fasciitis, which is related to strain and cold, resulting in spasm and contraction of the plantar tendon membrane at rest, and significant pain when moving down to the ground, but the pain is reduced or even disappears after a period of activity. In addition, it is also seen in middle-aged and elderly people who have degeneration of the heel bone and the formation of heel spurs. At the beginning, the heel spurs will stimulate the surrounding soft tissues when moving on the ground, resulting in obvious soft tissue edema and pain, but the surrounding soft tissues will gradually adapt to the edema state after a period of activity, and the pain will be significantly reduced or even disappear.
