My sister had exploratory laparotomy last august end. She was diagnosed with abdominal tuberculosis and she's on att since September. Currently on Rifampin 450, isoniazid 300 and ethambutol 800 and also pyridoxine 40. She is alright and her appetite is normal and gaining weight. But past few weeks her arms and hands are slightly hot to touch than others in my house. But she doesn't feel feverish or hot inside at all. Also oral temp is normal around 98 f using clinical thermometer. Please tell if there's any problem.
