Cramps on the outer side of the calf often occur in daily life. When this happens, it is mainly due to the muscle soft tissue injury caused by the patient’s overworked calf, strain, catching cold, standing for a long time, squatting for a long time and so on. After this situation, the patient should be instructed to rest in bed, avoid calf exertion, strain, avoid catching a cold, give hot compresses on the calf, with physical therapy instrument, acupuncture, moxibustion and other treatments. At the same time, oral medications that activate blood circulation and remove blood stasis can also be taken to relieve muscle damage. If the above treatments are ineffective, it is necessary to consider whether there is a problem with the cervical spine, and X-rays and CT films of the cervical spine should be taken to clarify whether cervical spondylosis exists. If there is cervical spondylosis, we should take treatment for cervical spondylosis, such as cervical spine braking, traction and oral neurotrophic drugs.
