The uncomfortable feeling in the feet may be caused by physiological factors such as prolonged walking or excessive weight bearing, or it may be caused by pathological factors such as plantar fasciitis and lumbar disc herniation. 1. Physiological factors: long time walking or excessive weight bearing can cause fatigue of the ankle, produce excessive metabolic products, and lactic acid accumulation can cause discomfort such as soreness, pain and fatigue of the ankle. 2. Plantar fasciitis: When walking for a long time or bearing too much weight, the plantar fascia rubs repeatedly, which can cause aseptic inflammation of the plantar soft tissues, resulting in pain, swelling and other symptoms of the feet. 3. Lumbar disc herniation: the herniated nucleus pulposus compresses the spinal cord and nerve roots, which leads to pain, numbness, weakness and other symptoms in the lower limbs and ankles. The foot is difficult to say the feeling, should pay attention to more rest to reduce weight-bearing, if the discomfort symptoms continue to be unrelieved, the patient should promptly consult a doctor for examination and standardized treatment after the cause is clear, so as not to delay the condition.
