Postpartum heel pain can be caused by walking too long, cold, fasciitis, bone spurs and other factors. 1. Walking for too long: Walking for too long can lead to lactic acid buildup in the muscles and localized swelling, thus causing postpartum heel pain. 2. Cold: If you don’t pay attention to keep your heels warm, the cold stimulation may lead to fasciitis and periostitis, which can also cause postpartum heel pain. 3. Fasciitis: If the fascia is stimulated by infection or inflammation, it can lead to localized swelling and pain, causing postpartum heel pain. 4. Bone spurs: a kind of osteophytes. If there is a bone spur, the pressure on the heel when stepping on the ground will increase significantly, causing irritation to the local nerves, which can also cause postpartum heel pain. If the above symptoms occur, the patient should pay attention to the timely consultation, do not delay the condition.
