<s>[INST] Hi Doctor. My three year and five month old daughter has been complaining of headaches for the last day or so also, she s has vomitted everytime the headaches come. This has happened twice in the last 24 hours. This is my first child, so i m not shore what this could be. I m very worried. Please help me with an answer to what this could be and what i should do? [/INST] Good morning.!! I understand that you are very much worried about your children situation. Your daughter might be suffering from migrant disorder (one of the types of headache) / sinusitis / viral infection / any other problem with the brain itself. Please consult your pediatric doctor for further (thorough clinical and labs if required) evaluation and treatment plan. Thank you, have a nice day.!!! </s>
