<s>[INST] My daughter is almost 7 yrs. old. On Friday and Saturday, she had a fever, on and off. Yesterday and today (for over 36 hours) no fever. Now she has been complaining that her chest and throat hurt - and says her chest pain is worse when she lies down? I m taking her to the doctor as soon as their lunch ends at 1:45, but was wondering what this could possibly be? Is it serious or perhaps just a pulled muscle? [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your daughter have symptoms of chest and throat pains and fever which is due to bacterial/ viral infection which is leading to respiratory tract infection. I would suggest you to visit pediatrician first once and get it examined and start treatment after proper diagnosis. Get blood test done to detect level of infection. Give full rest to your child with sound sleep. You should do warm saline gargles 3 to 4 times a day. Take ibuprofen one tablet twice daily. Throat lozenges one every 4 hours is helpful.  Chat Doctor.  Give soft foods to child to avoid irritation to the throat. You should take steam inhalation. Apply mist humidifiers in room.  You can give Metal P to child for fever. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
