Truthfully, ride it out for a few days if- 1. You are not dehydrated 2. Fever is controlled by aspirin, ibuprofen or acetaminophen 3. You aren't having difficulty breathing. Most likely you are suffering from a virus( flu)for which no prescription will be given. You Will pay upwards of a hundred dollars for a nurse or doc to tell you to stay hydrated, take Tylenol and rest. I'm a nurse and I gave the same advice for free. Hope you feel better soon.
I think that you should see a doctor immediately regardless of whether you are paying health insurance or not since your health matters a lot. The doctor will be in a good condition to find out what is wrong and give you proper medications.
