Muscle throbbing may be a physiological phenomenon, or it may be caused by hypocalcemia, motor neuron disease and other diseases. 1. Physiological conditions: muscle throbbing can also occur in cases of overexertion, tension, etc. It is a benign process and can be relieved by rest and relaxation without treatment. 2. Hypocalcemia: Calcium ions can inhibit muscle excitability. If there is a lack of calcium or vitamin D, sweating, diarrhea, etc., it will lead to a decrease in blood calcium concentration and increase neuromuscular excitability, resulting in muscle jumping or twitching symptoms. 3. Motor Neuron Disease: Motor neuron disease can be caused by infection and immunity, metal poisoning, and genetic factors. The first symptom of this disease is awkwardness and weakness in one or both fingers, and stiffness of the fingers. Flesh throbbing symptoms can occur due to damage to neurons. There are many other diseases that muscle throbbing predicts. If you can’t get relief or have other accompanying symptoms, it is recommended that you go to the hospital as soon as possible to clarify the cause of the disease and treat the symptoms.
