The healing time for the throat after the insertion of a breathing tube can vary from person to person based on individual circumstances, the duration of intubation, and overall health. Generally, the throat may take a few days to a couple of weeks to heal. Most people start to feel improvement within a few days, but complete resolution of discomfort or soreness can take longer.
A dry cough is also a common symptom after having a breathing tube, as the tube can irritate the throat and airways. It usually diminishes within a few days to a week as the throat heals. However, if the cough persists for more than a week, or if you experience other concerning symptoms such as difficulty breathing, fever, or significant pain, it's important to follow up with a healthcare provider. They can provide a proper assessment and treatment if needed.
