Thanks for posting your query.
Recurrence of abdominal pain
doesn't indicate recurrence of tubercular lymph
Does she has fever/ loose motion/ vomiting/ spasmodic abdominal pain?
She may have acute gastroenteritis
You should consult with physician and should go for repeat ultrasound
imaging to detect status of lymph nodes.
You should take proper treatment.
