The main causes of right calf muscle throbbing include physiological causes and pathological causes, physiological causes include excessive exercise, tension, etc., and pathological causes include progressive muscular dystrophy, lateral sclerosis of the spinal cord and so on. 1. Physiological causes: excessive exercise, tension factors stimulation, will lead to the right calf local nerve excitability increases, conduction increases, the muscle will produce involuntary contraction, resulting in the right calf muscle throbbing; Secondly, when the body is stimulated by the cold, it will lead to the muscle of the small blood vessel spasm, slow down the blood circulation of the muscle, the skeletal muscle trembling and heat production, may also appear in the case of the right calf muscle throbbing. 2. Pathological causes: muscle lesions, motor neuron disease and peripheral neuropathy, etc., may also appear in the right calf muscle jumping. For example, progressive muscular dystrophy, lateral sclerosis of the spinal cord, poliomyelitis, diabetes mellitus and so on. Pathologic causes can result in abnormal discharge of neurons in the right calf muscle and shortening of the muscle bundles, leading to abnormal contraction or spasm of the muscle and right calf muscle throbbing.
