A doctor highlights that a persistent, dry cough lasting more than an hour or occurring three or more times in a day is a key symptom distinguishing Covid from the flu or cold, which typically have milder or different cough patterns.
Many people are experiencing a lingering cough after a viral upper respiratory infection, even if they tested negative for COVID-19 and the flu. This persistent cough is likely due to prolonged inflammation in the airways, causing the body to continue producing mucus and experiencing bronchospasms. If you're dealing with this lingering cough, it's best to consult a healthcare provider who may recommend rest, hydration, and over-the-counter medications.
Lung cancer often goes undetected until it has reached an advanced stage, making early diagnosis crucial for better treatment outcomes. Oncologists highlight a commonly missed early sign of lung cancer: a persistent or worsening cough, especially in high-risk patients with a history of smoking. Other symptoms that may be overlooked include fatigue, hoarse voice, chest pain, bone pain, reduced appetite, and weight loss. If you're concerned about lung cancer, it's important to consult with a doctor for early recognition and treatment options.
