[|AI|]  Hello and welcome to Chat Doctor, High white blood cell (WBC) count is due to infection. Infections cause an increase in WBC counts. A differential count is required to know the type of infection -bacterial or viral. A high ESR is not specific for any disease, but it is elevated in chronic inflammations. Fever with enlarged lymph nodes and elevated ESR is an indication for conducting investigations for a malignant lesion e.g. lymphoma. Thus, consult your physician for aspiration cytology from the lymph node. Aspiration will detect the cells in the enlarged lymph node and thus, help to determine the cause of lymph node enlargement. Definite treatment will be started once diagnosis is confirmed. Thanks and take care Chat Doctor.
