If the patient has pain in the foot when squatting, it may be due to the following reasons: 1. It may be caused by the lack of mobility of the ankle joint, which is common when the patient has had a recent injury to the ankle joint, such as a fracture, dislocation or sprain and contusion here. During the treatment process, the patient needs to keep braking for a long time, and after the patient has obtained the relevant recovery, the ankle joint mobility may be insufficient due to prolonged braking. This may lead to pain when the patient squats, which may cause the ankle to move beyond its limits. 2. It is common for patients to have foot injuries, such as fatigue fractures of the metatarsal bones or old fractures in the heel bone, which may cause the above symptoms. 3. It is common for patients to have Achilles tendon lesions, such as Achilles tendonitis, which may cause similar symptoms.
