Hi Dear,
Welcome to Health Care Magic Team.
Understanding your concern.
As your describe in your query the symptoms mention are pointing towards bacterial or viral infection of
connective tissue layers of skull also known as meninges.Some times infections in other parts of the body like sinusitis ,
ear infection and diarrhea can lead to infection of meninges also known as meningitis.
Basically there are three kinds of meningeal infections viral ( most common), bacterial and fungal (very rare ) . viral infection is common and not very dangerous but bacterial infection van be dangerous .Diagnosis can be done by testing spinal fluid ,
blood culture,CT can of head .
I would suggest you to immediately consult neurosurgeon , so that treatment can be started as soon as possible .If its
viral meningitis symptoms will go away by its own within 2 weeks or your doctor can prescribe certain drugs for fever and anti viral medicines. If its bacterial then there is need of hospitalization your doctor can give intravenous antibiotics.
For now ask her to take complete rest .Give her sufficient fluids to prevent
dehydration.
Hope your concern has been resolved.
Best Wishes,
Dr. Harry Maheshwari
