You should worry and see a doctor about a persistent cough if it lasts longer than 3 to 4 weeks or if it is accompanied by any of these red flags:
Breathing Difficulties: Shortness of breath, wheezing, or chest pain.
Blood or Mucus Changes: Coughing up blood, blood-streaked phlegm, or thick pink/foul-smelling mucus.
Systemic Symptoms: Unexplained weight loss, drenching night sweats, or a high fever that won’t go away.
Hoarseness or Changes: Unexplained voice changes or a cough that gets progressively worse instead of better.
