Duh ... IF you actually went to a doctor ... (1) they would have told you what it is, or (2) you need to find a different doctor.
I have chest/stomach pains, a 101ish fever, and a sore throat (I went to the doctor and got a step test and it came back negative). Does anyone know what this could be? I'm a 14-year old female and I DON'T have a cough/cold.
You're 14 years old. If you went to the Doctor, what was the Doctor's diagnosis? If you didn't go to the Doctor, what do your parents say you have? Don't trust strangers on the Internet to diagnose you. Go to your mom and dad - that's what they are there for.
If you have been to the doctor and they didn't give you any medication you have a virus and it just needs to run its course. Drink fluids and get some sleep.
