Hi, From what you said, she is suffering for fever, body stiffness and abdominal pain, for over one month. She had already received two courses of antibiotics. Although the details given are not sufficient for a firm conclusion, if I were your treating doctor, after a thorough physical examination to look for pallor, lymph node enlargement, enlarged liver/spleen and abdominal tenderness, I would have ordered few tests like blood count with ESR, urine routine, serum Widal and a peripheral smear and proceed further accordingly. Your doctor will guide you. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Muhammed Aslam TK, Pediatrician
