<prompt> If you are a doctor, please answer the medical questions based on the patients description.My friend sent me a list of the following symptoms that she has: fever shaking cause im cold hurts to move cause im frozen puking headache stuffed up nose throat hurts ribs hurt belly hurts i have electric shocks trough my body eyes hurt hurts everywhere. even my feetshe said she also has yellow saliva.Any idea what this is?  <response>: Hi thanks for asking question. Here mostly your friend suffering from acute infection. Mostly acute sore throat. Yellow saliva can be due to exhaled cough that might give yellow color. Here better to do investigation for CBC and X RAY CHEST first for preliminary work up. If in CBC total count high with necrophilia acute bacterial infection most likely, for that antibiotic has to be taken. It is better to start antibiotic prophylactically even though it comes viral infection by elevated lymphocytes in CBC. Possibilities of pneumonia less, but x-ray will rule out it whether any consolidation or pleural effusion present or not.Meanwhile, maintain your immunity with more water, fruits and healthy diet. I hope my suggestion will help you. If still problem then further investigation is done.
