There's a weird feeling which may happen under the forefoot which is typically described as a feeling that the sock is scrunched up beneath the toes, but when you looked at it, it is fine. The feeling is commonly described and is often baffling. Most likely the feeling is because of an issue with a ligament at the base of one or more of the metatarsophalangeal (toe) joints of the feet named plantar plate dysfunction. About each joint, there is a strong covering known as the joint capsule. Regions of each joint capsule are thicker and these are the ligaments which guard and stabilise the joints. Underneath the base of the metatarsophalangeal joints, that joint capsule is thicker to make what is known as the plantar plate. You possibly can strain or even get a minor tear in that plantar plate, which in turn causes that sensation of a sock which feels like its scrunched up below the toes.
The pain of a plantar plate tear usually commences slowly below the ball of the foot and might be preceded by that unusual bunched sock sense. The common sign of plantar plate dysfunction is soreness on palpation of the region of the plantar plate. An expert clinician will move the joint in such a way to identify if the plantar plate is injured. A definitive diagnosis may be done using a diagnostic ultrasound, but it can be pretty evident to a proficient clinician on assessment. Typically the first treatment methods are taping to hold the toe directed down to relieve the pressure on the ligament. A metatarsal pad can be often used to help reduce the stress on the plantar plate. This often fixes most cases of plantar plate dysfunction and get rid of that weird experience of a scrunched up sock beneath the ball of the foot. In the event that those conservative treatments really don't help, surgical repair of the partial or complete tear of the ligament is often carried out.
