Thanks for posting your query.
You may have meningitis
with raised intra cranial pressure or general malaise because of systemic infection.
You should consult with physician/ neurologist
and should get thorough check up of whole body.
By clinical examination, involvement of meninges may be detected.
You should also undergo following blood investigations: complete blood count
, urine examination, widal test, chest x ray. Blood culture
& sensitivity and spinal puncture if needed.
You should also get your blood pressure checked.
