The following emergency methods can be used for thigh root cramps: First, the patient should first keep braking and rest, and relieve the muscle spasm by means of reverse stretching. At this point, the first thing to do is to determine where and in what direction the cramp appears. If the symptom is in front of the thigh root, the patient should stretch to the back of the thigh root. In this case, the patient can first stand on one foot using the lower limb of the healthy side, lift the foot of the painful area to the rear, and pull it upward with the hand to the rear. In this way, the muscle spasm in the front of the hip joint is relieved. A similar approach can be taken for pain or spasm in other areas. At this time, if there are other people around who can help, the patient can lie on his back on the floor or bed and ask other people to take a similar way to perform passive stretching, which is much more effective. Second, the patient can use hot compresses on the painful area, for example, hot water bags can be used for more than 10 minutes. Third, the patient can take gentle massage to the painful area, such as the use of kneading or palm root kneading, massage it. Fourth, patients can drink juice or light salt water to replenish electrolytes after the symptoms are relieved.
