Hello, You are suffering from a bout of flu. Since you have tonsillitis, you may have to take an antibiotic course to treat the infection. Take betadine gargles twice daily and a painkiller like Tylenol to alleviate the pain. The diarrhea is most likely viral in origin and therefore will run its course. Take plenty of fluids in the form of water and ORS. You can take a probiotic and prebiotic respules which will help to restore the intestinal flora and help in faster recovery. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nazma.amman
