When should a person with common cold consult doctor?

It's generally advisable to consult a doctor if your cold symptoms are severe or persistent, or if you have underlying health conditions. Here are some scenarios when you should consider seeing a doctor for your cold:

1. Worsening Symptoms: If your cold symptoms are getting worse over time instead of improving, you may need medical attention. This is especially true if your fever is high and lasts for more than 3 days, or if you have shortness of breath or chest tightness.

2. Persistent Symptoms: If your cold symptoms last longer than 10-14 days without any improvement, it's a good idea to consult a doctor. Prolonged symptoms may indicate a more serious underlying condition.

3. High Fever: A fever above 100.4 degrees Fahrenheit (38 degrees Celsius) or one that doesn't respond to over-the-counter medications may require medical attention.

4. Severe Nasal Congestion: If nasal congestion is severe to the point where it's difficult to breathe, impacting sleep or daily activities, you may want to see a doctor. They may recommend treatments to relieve the congestion.

5. Facial Pain and Pressure: Severe pain or pressure around the sinuses, especially with a high fever, may indicate a sinus infection, requiring medical evaluation.

6. Ear Pain or Drainage: If your cold is accompanied by severe ear pain or drainage from the ear, it could signal an ear infection and necessitate a doctor's visit.

7. Yellow or Green Nasal Discharge: Discolored nasal discharge (yellow or green) may indicate a bacterial infection, suggesting the need for antibiotics.

8. Chronic Health Conditions: If you have underlying health conditions like asthma, chronic obstructive pulmonary disease (COPD), diabetes, or a compromised immune system, it's important to consult a doctor早めにfor any respiratory symptoms, including those related to the common cold.

9. Severe Fatigue or Weakness: Feeling extremely fatigued or weak with your cold may warrant medical attention, especially if it impacts your daily activities significantly.

10. Medication Interactions: If you're taking other medications, it's essential to check with a doctor before using over-the-counter cold remedies, as some medications may interact and cause adverse effects.

Remember, while the common cold is usually self-limiting and resolves within a few weeks, seeking medical advice can provide peace of mind and ensure timely management of any complications or underlying infections.
