When a cramp occurs in your arm, you should immediately stretch the muscles localized to the cramp. For example, when a cramp occurs in the biceps muscle, you must immediately straighten the elbow joint. If the pain is relieved or disappears after stretching, you can stop stretching. If the symptoms are not relieved after stretching, we should immediately use manipulative massage treatment that will reduce the spastic pain of the muscle that occurs because of the cramp. Generally use the shaking method first, so that the arm is fully relaxed, and use the light kneading method locally to gradually increase the amount of local blood circulation, so that the cramped muscles can be gradually loosened. If the symptoms are not relieved, you can gradually increase the intensity of the manipulation, and you can also take oral clozoxazone tablets and apply blood-activating and pain-relieving tincture topically. The use of acupuncture treatment, as well as physical therapy, are effective for cramps and the local pain symptoms that occur after cramps.
