Hello
As you mentioned that you have taken clindamycin300 mg orally for 10 days ,but you didn't mention the name of disease for which you took this antibiotics .
Clindamycin never produces such symptoms like
sore throat , enlargement of lymph nodes , difficulty in swallowing , drinking .
After discharge from hospital and in spite of
azithromycin and clindamycin treatment , you are still having leucocytosis ( increased level of WBCs) ,this clearly indicate that still you are having infection ( most probably ).
Enlargement of lymph node in and around cervical area of neck may be due to these possibilities , these include :
1
Septic pharyngitis , diagnosis can be confirmed swab culture from throat.
2
Tubercular lymphadenitis . diagnosis can be confirmed by
biopsy for enlarged lymph nodes.
3 HIV ,infection if there is contract history .
however , there are so many possibilities of such enlargement of lymph nodes , like bacterial , viral ,fungus , carcinoma.
But I recommend you please consult another physician and get his opinion at earliest.
Good luck.
