It's common to experience a buzzing sensation in different parts of the body when undergoing a lot of stress. Many people describe feeling nervous, anxious, or stressed as having a "case of the nerves" and may experience trembling, shaking, or vibration. Stress can affect the body in various ways, and these physical symptoms are just one manifestation of its impact. It's essential to manage stress through techniques such as exercise, meditation, or seeking professional help, if necessary. Taking care of your mental and emotional health is crucial for your overall well-being.
