When Should You See a Doctor for a Cold?
Most colds resolve on their own within 7-10 days without medical treatment. See a doctor if symptoms last longer than 10 days, you develop a high fever (over 103°F), symptoms suddenly worsen after improving, you have difficulty breathing or chest pain, or you have underlying health conditions that increase risk of complications.
Key Takeaways
- Common colds are caused by viruses (usually rhinoviruses) and cannot be treated with antibiotics.
- Green or yellow mucus alone does not indicate bacterial infection - it is a normal part of cold progression.
- Ear pain may indicate an ear infection requiring antibiotics.
Explanation
Common colds are caused by viruses (usually rhinoviruses) and cannot be treated with antibiotics. Typical symptoms peak around days 2-3 and gradually improve. Home treatment includes rest, fluids, over-the-counter symptom relief, and time. Most healthy adults recover fully without medical intervention.
Warning signs requiring medical attention include: fever over 103°F (39.4°C), symptoms lasting more than 10 days, symptoms that improve then suddenly worsen (may indicate secondary bacterial infection), difficulty breathing or shortness of breath, persistent chest pain, confusion or altered mental state, and inability to keep fluids down.
Higher-risk groups should be more cautious. See a doctor sooner if you are over 65, have asthma, COPD, heart disease, diabetes, or a weakened immune system. Infants under 3 months with fever need immediate medical evaluation. What seems like a cold could be flu, strep throat, COVID-19, or other conditions requiring different treatment.
Things to Know
- Green or yellow mucus alone does not indicate bacterial infection - it is a normal part of cold progression.
- Ear pain may indicate an ear infection requiring antibiotics.
- Persistent cough after cold resolves can last weeks but usually does not require treatment.
