Thanks for writing to H.C.M. for your query.
I have gone through your query regarding sore throat
along with it there is enlargement of neck lymph
nodes. As you said that you have already taken two rounds of antibiotics but still soreness in throat is persisting and recentally cervical lymph nodes are also enlarge.
Listening your history of illness I would like to tell you that you still need antibiotic. But now you take it after culture and sensitivity reports and also antibiotic will be decided on the basis of culture report.
Now you have developed enlarge cervical lymph nodes therefore they should also be investigated by FNAC testing to know the nature of disease so that they can also manage accordingly.
