Dear doctor May I ask a question? Three weeks ago, my mother (72years old) suffered from flu associated with productive cough and was treated with an antibiotic and becomes well with no side effects on lungs. Associated with these symptoms, there were nausea and diarrhea. These two symptoms are present until now. The stool analysis and culture indicate: no blood, no mucus, no bacteria, no parasites, no fungi, and no yeast cells. However, it indicates occasional fecal leucocytes and 2 pus cells. What do you think the problem is?I am very sorry for disturbance, but I really need your help.Thank you very much in advance.Best regards Yours truly, Samira A Ali Egypt
