Sudden jerking for a minute may be caused by calcium deficiency or epilepsy, or it may be physiologic myoclonus. Treatment rest, medication, surgery, etc. If it is caused by physiologic myoclonus, it is easy to occur when you are tired, resting or just before going to sleep, and can be improved by resting sufficiently. If it is caused by calcium deficiency, as calcium deficiency in the body will reduce the level of calcium ions in the blood, the lowering of blood calcium will increase the excitability of the muscles, making the myofascia undergo abnormal spasm in response to small stimuli, thus inducing the appearance of cramps and jerks, which can be treated by applying calcium supplements under the guidance of the doctor, such as oral calcium tablets. If it is caused by epilepsy, through drugs, surgery, etc., oral antiepileptic drugs, such as carbamazepine, oxcarbazepine, sodium valproate, etc., can be taken as prescribed by the doctor. If it is secondary to epileptic seizures, the disease factors causing epilepsy need to be removed in time, such as removing the tumors in the brain and controlling intracranial infections. Sudden convulsions, should be timely consultation, identify the cause of the disease after targeted treatment, do not blindly self-medication.
