Step 4: Read and complete the decision guide to learn more about your symptoms.
Fever in Adults
Okay, from your answer, you could have:
- Strep throat -- a bacterial throat infection that often causes headache
- Mononucleosis -- a viral infection that often causes terrible fatigue, sore throat, and swollen lymph nodes ("glands"), and that can last for weeks
- A cold or flu -- viral infections that may cause sore throat, muscle aches, fever, and headache.
Call your doctor's office for advice. If you have strep throat, you will need antibiotics. Sometimes influenza is treated with an antiviral medication, such as oseltamivir (Tamiflu).
We're almost done.
Have you had any abdominal pain, vomiting, cramping, or diarrhea?
