Thanks for using Healthcaremagic,
After going through all your details,Widal test
is done for Typhoid fever
but it is not specific and Typhoid fever is unlikely to persist for 55 days?
You are given Benocide forte for eosinophilia which is antihelminthic drug used for Filaria/ Tropical Eosinophilia
If all investigations are done and fever is still persisting your should get hospitalized and properly investigated as case of PUO (Pyrexia of unknown origin).
There are many causes of such fever we need to know first diagnosis then it can be treated depending on cause.
In such cases hidden infection like Tuberculosis
,and Malignancy needs to be ruled out by proper investigations like Bone marrow
, CT scan, MRI, if required Biopsy to know the cause.
Please consult good Physician and once cause is detected treatment would depend on diagnosis.
Hope this Helps.
