Parkinson's/ Nerve Tremors:

The most common cause of shaky hands is essential tremors. This neurological disorder causes frequent, uncontrolled shaking. Other causes of shaky hands include stress, anxiety, over worrying, overthinking negative thoughts and seizures. While there's no much cure for most of the hand tremors in allopathy.

Prescription medications, Naturopathy, Ayurveda, Herbs, and lifestyle changes may provide relief, depending on the cause.
