Hello, my name is Dr.Dorina Gurabardhi. I understand your concern. A low-grade fever is often classified as an oral temperature that is above 98.6° F (37° C) but lower than 100.4° F (38° C) for a period of 24 hours. Fevers, though uncomfortable, play a key role in helping your body fight off many infections. Some advices that I can give to you are: 1)Rest and drink plenty of fluids. 2)You can also place a cold, damp washcloth on your forehead or the back of your neck while you’re resting 3)take ibuprofen in case that the symptoms continue. Hope my answer was helpful, if you have any other questions I ll be glad to help, thanks!
