Viral infection? . Your symptoms are consistent with a viral infection. Use acetamenifen or Ibuprofen for fever or aches and keep well hydrated. Let your body's immune system do the rest. If your symptoms persist for more than a week, have your doctor check you. If fever occurs let your doctor know.
