Hi,
I had gone through your question I can understand your concern about your father. In case he doesn't have any
tuberculosis he will be having the same side effects as he feels it now.
First, after all, doctors do not start anti-tuberculosis therapy without having proper clinical and pathological finds, so there are signs and symptoms of TB that is why the medication is there.
Second
weight loss is one of the major clinical findings with other signs and symptoms associated.
7 mm of
cyst is not much concern and most of the times these cystic lesions limit on there own or by medication only. Don't bother about it.
You must not discontinue the therapy without the consultation of a doctor.
You need to provide him with a properly balanced diet and proper timing of medication and also take every decision after consultation with your family physician.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
