Thanks for your question on Healthcare Magic. I can understand your concern. Since you had seizures in the past, we should definitely rule out recurrence of pulmonary this seizure episodes in your case. Shivering of whole body can be due to seizure activity. And diabetes and hypertension can precipitate seizure activities. So better to consult neurologist and get done clinical examination, MRI brain and EEG (electro encephalo gram). You may need regular anti epileptic drugs on the basis of above results. If all these reports are normal then get done vitamin B12 level as deficiency can also cause similar symptoms. And if deficiency then you will need supplements too. Don t worry, you will be alright. But first rule out seizures. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
