What Are the Causes of Sore Throat Without Fever?

Sore throat without fever has a variety of different causes and commonly seen in primary care. Some of the most common reasons include a viral, bacterial or fungal infection, seasonal allergies and acid reflux. Viral, bacterial or fungal infections may often not cause fever but will often be accompanied by other symptoms like runny nose or nasal congestion. Seasonal allergies can lead to a sore throat due to irritation from the seasonal allergen, and may not necessarily be accompanied by other allergy symptoms like runny nose or itchy eyes. Lastly, untreated acid reflux may lead to sore throat because stomach acid irritates the throat.
