The main cause of muscle stiffness after three months of gastrocnemius strain is caused by gastrocnemius muscle adhesion. Treatment mainly includes conservative treatment and surgical treatment. 1. Conservative treatment: Most of the muscle stiffness caused by muscle strain can be improved by conservative treatment. Conservative treatment mainly includes hot compresses, massage, infrared physical therapy, deep microwave, etc. The purpose is to accelerate blood circulation and speed up the process of muscle stiffness. The purpose is to accelerate blood circulation, faster excretion of metabolic products, release the fascia, and help the body repair itself. 2. Surgery: Surgery can be considered for patients who have been ineffective in conservative treatment, patients who are seriously affected by normal life and work, or patients with severe adhesion and limb motor dysfunction. Surgery is adhesion release surgery, but the surgery will cause oozing and new adhesions, so patients need early rehabilitation training after surgery to avoid the occurrence of secondary adhesions. For the same disease, patients with different physical conditions and different stages of the disease have different treatments and should be treated in a standardized manner under the guidance of a doctor.
