My mother suffering with cough from 3 months. We did the Tb test. It shows negative. We have taken an X-ray. In that doctor told that a little bit nimmonia inside the lung tubes and she had typoid. He gave some tabs for both but the cough was not reducing and getting worse in night. Why it's happening? How to reduce cough .I'm attaching doctor prescription. In the tablets list we are using glavo 500 instead of forbact er 300 in the list due medicine  unavailability. Please tell me what to do
