Hi & Thanks for the query in HMC.
by word Shivering as i understood is tremor,right !
Tremors are caused by problems with the nerves supplying certain muscles. They may affect the whole body or just certain areas, as with hand tremor.
Types of tremors include:
Drug-induced tremor (tremors caused by certain drugs),
Essential tremor (no known cause),Familial tremor (runs in families),
Other causes of tremors may include:
Alcohol withdrawal,
Cigarette smoking,
Hyperthyroidism,Parkinson's disease,
Pheochromocytoma,Too much caffeine,Use of certain medications,Wilson's disease
All people have some tremor when they move their hands. Stress, fatigue, anger, fear, caffeine, and cigarettes may temporarily worsen this type of tremor. My advise you to book appointment with your primary Physician/ Family Physician.
I think this will help you ..
Regards,
