My son had fever a few days back which lasted for about 5 days. We gave him P120 drops as suggested by his doctor. He has recovered now, however whenever we check his temperature, it always shows to be around 98.1 to 98.7° F. The temperature is taken under his arm pit using both Mercury and digital thermometers. We were told that one degree is to be added to the displayed temperature when measured under armpit, which makes it 99.1 to 99.7. But his body doesn't show any sign of heat or warmth and is always cool. Why is it so? Does this mean he still has a fever or is this normal?
