Hi docs, what is the reason, my mother sometimes she feels that her body is trembling. why? and what is that? and sometimes she feels like vomiting.

Mom's condition: This must be unsettling for you. You see your mother in this way. These symptoms could be from a wide variety of circumtsances, including a viral problem, food, supplements, medications, alcohol, or other medical or neurological conditions. I would find a quiet time to sit alone with her (since people and mothers especially, are private about their health) to share your concern for her health.
