Running arch pain requires general treatment, medication, physical therapy and surgery, etc. It may be related to lactic acid accumulation, plantar fasciitis and muscle strain. 1. Lactic acid accumulation: excessive running causes accumulation of lactic acid in the foot muscles, which can cause physiological pain and can be relieved after rest. 2. Plantar fasciitis: Aseptic inflammation of plantar fascia due to trauma, cold, excessive walking and other factors. Oral analgesics such as ibuprofen and local injection of glucocorticoids such as prednisone can be prescribed. It is also feasible to apply hot compresses, bake electricity and other physical therapy; if conservative treatment is ineffective, endoscopic minimally invasive release surgery, plantar fascia partially cut off, and so on. 3. Muscle strain: attention should be paid to reduce the activities of the foot, so that the plantar muscles can get rest; follow the doctor’s instructions to take oral ibuprofen and other analgesics, epirubicin and other myosotropic drugs; if the conservative treatment is ineffective, consider minimally invasive surgical treatment. There are many other causes of arch pain when running, such as flat feet, fatigue fracture, etc., if the rest does not relieve, it is recommended to go to the regular hospital in time, improve the examination to clarify the cause of the disease, standardized treatment under the guidance of the doctor, do not use their own medicine.
