There are many reasons for arm muscle throbbing, which can be caused by both physiological and pathological factors, such as tension, peripheral neuropathy, hyperthyroidism and so on.
1. Physiological factors: such as after exercise, cold or tension, etc., can lead to muscle throbbing.
2. Peripheral neuropathy: the etiology is complex, due to structural or functional damage to the peripheral nervous system leading to the appearance of muscle jumping.
3. Hyperthyroidism: Due to the body’s hypermetabolism, the system’s excitability increases, which is mainly manifested as hyperphagia, emaciation, palpitations and sweating. Some patients may have trembling hands and jumping arm muscles.
Arm muscle jumping may have other causes, such as tetany, etc. If muscle jumping is combined with other symptoms and manifestations, it is recommended to go to the hospital in time.
