The possible causes of muscle throbbing at the lower part of the hand include muscle fatigue, calcium deficiency and motor neuron disease.
1. Muscle fatigue: muscle fatigue caused by prolonged overexertion of the hand muscles can cause spasm and abnormal contraction of the local muscles, and the self-conscious symptom of muscle throbbing will occur. In this case, appropriate massage of the hand muscles, pay attention to rest, can be gradually relieved.
2. Calcium deficiency: Calcium deficiency can cause abnormal excitation of skeletal muscles, and then muscle twitching and other symptoms, manifested as paroxysmal muscle twitching, throbbing and other symptoms. Combined with the blood calcium test can be clearly diagnosed, can consider taking calcium gluconate, calcium carbonate D3 and other drugs treatment.
3. Motor neuron disease: it is a chronic neurological disease, its etiology and pathogenesis are still unclear, often with muscle atrophy, muscle throbbing as the first symptom, can appear at the same time the symptoms of upper motor neuron damage symptoms and lower motor neuron damage symptoms, EMG and other neurophysiological examination can assist in the definitive diagnosis.
The causes of muscle throbbing are many, and may also be caused by peripheral neuropathy, upper extremity vascular disease and other factors, it is recommended to consult a doctor in a timely manner, improve the blood electrolyte test, electromyography and other related examinations, to clarify the diagnosis, and according to the cause of the development of a reasonable treatment program.
