Hi
welcome to HealthCareMagic
First part of history given by you is suggestive of recurrent infections ,twice of gastrointestinal tract and once upper respratory infections , most likely viral.
Now the issue is of cervical
lymph nodes and 6 months treatment .If I were your treating
pediatrician I would like to examin and evaluate for the cause of enlarged cervical lymph nodes .Have you noticed earlier these enlarged lymph nodes
or it is a new finding ? Size of lymph nodes?.Are they painful ? Is there
fever this time ?Is there any family history suggestive of
tuberculosis ? Depending upon history and examination and invetigations we shall be able to lead to a conclusion what is cause of enlarged lymph nodes.If there is short history it can be simple viral or bacterial infection ,in later case will resolve with a course of antibiotics.Question of tuberculosis and 6 months treatment only arises if they are found to be tubercular.Has she been evaluated for that ? If found positive she can be cured with a 6 month course of antitubercular drugs .In my opinion she needs proper evaluation for cause of enlarged lymph nodes and to decide accordingly.You have not mentioned any investigation done.Previous episodes of fever do not seem to be related to lymph nodes enlargement.
Do revert back with these inputs so as to reach upon any conclusion.
Hope I answered your query
thanks
