My 11 year old daughter started vomiting early hours of Friday morning.  She stopped by 1pm on the lunchtime.  She then ate at 9.30pm and vomited immediately after. Yesterday she ate something and vomited again straight after. Today, she hasnt vomited after eating, but she has red blotches on her face and feels quite sick.  Is this just a normal virus, which should clear naturally?
Red blotches on skin may be due to many causes like allergy, rosacea or Chat Doctor. Physical examination is required to come at diagnosis and also whether it will subside on itself or medication is required. One important thing we need to know is whether it is itchy or not, fever is there or not and also her vital parameters. We cant straight away tell based on history like its due to virus and clear naturally. It is better you consult a qualified physician. She may require antiemetic, anti bionics and antipyretic medication and also diet should be easily digestible, less oily, less spicy, more fresh fruits, and also she requires rest till she becomes fully fine.
