Patients can identify whether their calves are muscular legs by the following methods: a. Patients can take a tiptoe heel position. For example, the patient can take a standing position, or a sitting position, and gradually tiptoe on his or her heels at this time and maintain this position. If you take such a posture or position, you can see that the muscles in the calf area have a significant bulge, or the muscle line is more obvious, most of the time it is muscle leg. If there is no such situation when doing this posture, it may be caused by too much obesity in the calves. Second, the patient can take the way to lift the calf to identify. At this time, the patient can take the supine position, and afterwards take the hip flexion, knee flexion, and put the lower leg in a horizontal position. After that, the patient can use his hand to touch the calf area, if at this time can feel the calf area is very soft, most of the time is not muscle legs. However, if the tension of the calf is still high and hard, it may be a muscle leg.
