The causes and treatments of plantar pain are mainly as follows: First, heel pain syndrome is the most common cause of plantar pain in middle-aged and elderly patients, and if diagnosed, extracorporeal shock wave therapy and closed injection can be used for pain relief. Generally after 1-2 courses of treatment, the painful symptoms of achalasia will gradually ease or even disappear completely. Usually, attention should also be paid to protecting the sole of the foot to avoid excessive stress on the bottom of the foot and adverse stimulation. Second, if the pain is caused by trauma to the heel, especially a comminuted fracture of the heel bone, active repositioning and fixation treatment is required. Some patients also need to undergo surgical repositioning and internal fixation and bone grafting to restore the continuity and integrity of the fracture, which can provide rapid relief of plantar pain symptoms. Patients also need to undergo rehabilitation after surgery to promote recovery.
