If I have more to 102.7 *f for 4 days what I need to due?

See a doctor? Difficult to know what you have without more information. What other symptoms do you have? How old are you, where do you live, with whom have you been in contact, do you contact animals, etc. See your local doctor if not better in next several days.
It depends. I would need to know your age and what other symptoms you have before could help you. You should see you personal physician.
