Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You are presenting multiple symptoms that your daughter has: eye pain, head pain, musculoskeletal pain, nasal congestion, and vomiting. Multi-systems are involved and it seems like she has a flu-like illness. She also has disordered sleeping. A child her age should get 10-11 hours of sleep a night and easily awaken in the morning. She ought to have a nighttime routine: a warm bath or shower at night, followed by about half an hour of reading a book for pleasure in bed, no screens in bedroom (cell phone, iPad, computer, TV), no loud noises outside of her bedroom that she can hear. A child her age should get 10-11 hours of sleep per 24 hours. This doesn t have to be all at one time. For example, she could sleep for 9 hours through the night and have a one hour nap just as she arrives home from school in the afternoon. It will be a good idea if you and your daughter together set her bedtime and be insistent that she get up in AM with enough time to get ready for school and eat a GOOD breakfast. For the flu-like illness she can take Ibuprofen or Acetaminophen for pain or fever and plenty of fluids so she doesn t become dehydrated and having plenty of fluid in her body will help decrease her muscle pain. I hope this helps and she gets well soon. Please return when more questions arise.
