A cold typically lasts about 7 to 10 days, but if it is not going away, it could be due to several reasons:

• You may have developed a secondary bacterial infection such as sinusitis or bronchitis, which can prolong symptoms and require medical treatment.
• Underlying conditions like asthma, allergies, or sinus issues can make cold symptoms last longer or feel more intense.
• A weakened immune system due to stress, poor nutrition, or chronic health issues can delay recovery.
• Environmental factors like dry air, dust, or mold exposure can irritate your respiratory system and extend symptoms.
• Sometimes, what seems like an unresolved cold might be another viral infection or a sinus infection rather than just the common cold.
• Not getting enough rest, fluids, or managing stress can also cause cold symptoms to linger.

If your cold lasts longer than two weeks, or symptoms worsen instead of improving, it is important to see a healthcare provider for evaluation and possible treatment.
