How to Tell the Difference Quickly

Cold Symptoms

Colds usually start with a scratchy throat or congestion and progress slowly. If symptoms remain mild with no high fever, you're likely battling a common cold. Staying hydrated and resting is key, but if symptoms worsen, WithCare Urgent Care can evaluate and treat you promptly.

Flu Symptoms

The flu hits fast and hard. High fever, chills, body aches, and exhaustion are classic signs. If you feel suddenly very sick, it’s probably the flu. Antiviral treatment works best when started early, so stopping by WithCare Urgent Care for rapid flu testing is a smart decision.

Allergy Symptoms

Allergies persist long-term and often flare up during certain seasons in Hurst, Euless, and Bedford. Itchy eyes, sneezing, and clear nasal drainage are hallmark allergy symptoms. Since allergies aren’t caused by a virus, they won’t cause fever. If allergies disrupt your daily life, WithCare Urgent Care can recommend effective relief options.
