Hello. Welcome to hcm.
High degree fever not coming down to antibiotics should be investigated. Typhoid
may be there but it should be gone by takin antibiotics for 20days.
I advice you to undergo fever profile which includes testing for malaria
,typhoid. If endemic for other diseases like dengue
,chikangunya or parasite borne infection,it should be checked. Antibiotics should be stopped unless infection and sensitivity proved. You should be checked for infections or abscess
in body and then treated accordingly.
All the best
