<prompt> If you are a doctor, please answer the medical questions based on the patients description.due to nervousness my hand always get sweat vibrate ? due to this i always depressed fear, i always try to avoid everything in my life ?  <response>: Nervousness, sweating and vibrating are due heightened sympathetic nervous system activity. Anxiety can cause these symptoms. Try these lifestyle modification: Eliminating caffeine, start an exercise program, improve your diet, and get support from family and friends. Try some relaxation techniques like Yoga, meditation, and deep breathing exercises. Dealing with worries is also one technique; like learning to postpone worries, and learning to accept uncertainty in your life. If nothing works there are some medications which reduce sympathetic activity, like propranolol. Best wishes,
