Similar : Similar to taking a temperature in a child, you add a degree to the axillary (armpit) temperature in an adult. An "average" body temperature is 98.6 degrees f and anything over 100.5 degrees f is considered a fever. (you can get your body temperature up to 100f by being in hot weather or exercising). You may get slightly different readings since body temperature can fluctuate. When possible, we usually recommend the under-the-tongue temperature with a closed mouth for an older child or adult since this is one of the most accurate ways to assess body temperature.

Temp: Axillary(arm pit) temperatures are not very accurate. The question of fever is probably mute since you describe symptoms of infection where a fever would not be unexpected anyway. You are describing flu like symptoms for the most part. The burning when peeing could be from a urine infection though. Not knowing the patients age or other medical problems, it is probably a good idea to see a doc.
