Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of headache, warm body, stuffy nose and sneezing can be due to few causes like Viral infection or upper
respiratory tract infection,
sinusitis etc..
I would suggest you to give her a course of antibiotics like
Amoxicillin, anti-inflammatory painkiller like
Ibuprofen, tylenol to stabilize body temperature, steam inhalations, decongestants like Pseudoephadrine and anti allergics like Benadryl..
Steam inhalations and warm saline gargles will help..
Using a humidifier in room can ease in breathing moist air..
Give her ample of rest and sipping warm water throughout the day..
Feed her with warm fluids like soups, broath etc..
Give her a
soft diet..
In case if still there is no improvement consult an Otolaryngologist or Paediatrician and get evaluated..
Hope this information helps..
Thanks and regards.
