Thanks for contacting with your health concern
1. As symptoms are sudden, [mainly
fever, headache] thus an immediate visit to ER [emergency room] is warranted to exclude
meningitis.
PS. An immediate
Neurologist opinion and C.T. scan [if needed] is required since best treatment is to address the underlying cause.
2. If the examination and investigation come normal, I do check the following signs in my patient: [for headache/ fever]
i. check blood pressure.
ii. check sinus tenderness over maxillary & frontal
sinuses and look for any focus of infection in teeth, tonsils, and ears.
iii. check tenderness on the nape of neck or pain on neck movements.
iv. look for any painful/red-eye and [if present] ask for ophthalmologist opinion.
PS. If the fever doesn't reduce within 3-4 days of antibiotic treatment, ask for Hb%, WBC, ESR,
Widal test, Urine, and X-ray chest.
