There are many reasons for pain under the sole of the foot, and common causes include plantar fasciitis, metatarsal tendonitis, and flatfoot syndrome.
1. Plantar fasciitis: It is a localized inflammation of the fascia caused by the plantar muscles being impacted by external forces or walking for a long time, which leads to strain of the plantar muscles. It manifests itself as pain under the sole of the foot, especially when walking. It is common in people who wear high heels for a long time, are obese and stand for a long time.
2. Metatarsal tendonitis: it is due to the long-term large amount of foot movement or degenerative changes caused by the metatarsal tendon membrane aseptic inflammation, which leads to the symptoms of pain in the soles of the feet.
3. Flatfoot: refers to the low or disappearing arch of the foot. It is usually caused by abnormalities in the bones and muscles of the foot, or due to genetic factors. People who are overweight and stand for long periods of time can also suffer from clubfoot. This condition causes pain in the soles of the feet when walking or standing for long periods of time, and is usually relieved by rest.
In addition to the above reasons, osteoporosis, degenerative changes, damage to the ankle blood vessels and nerves can also cause pain under the sole of the foot. If any of the above symptoms occur, it is recommended to consult a doctor in time to identify the cause of the disease and to carry out targeted treatment with the help of the doctor.
