Coughs are common, especially during respiratory-infection season. Many improve without specific treatment, but not every cough follows the same pattern.
What makes a cough worth checking?
A cough may deserve medical assessment when it is persistent, worsening, associated with significant fever, wheezing, chest pain, shortness of breath, coughing up blood or a clear decline in general condition.
It is also worth reviewing when symptoms initially improve and then return, or when a cough repeatedly occurs in a similar pattern.
A cough is not a diagnosis
Possible causes include viral infection, bacterial chest infection, asthma, allergy, post-nasal drip, reflux, medication effects and other respiratory conditions. The timing and associated symptoms help narrow the possibilities.
What might a GP do?
The doctor may listen to the chest, check oxygen levels or other observations where appropriate, assess the throat and upper airway, and decide whether medication, testing, imaging or follow-up is needed.
Do I need antibiotics?
Not automatically. Most uncomplicated viral respiratory infections do not benefit from antibiotics. Antibiotics are used when the clinical picture supports a bacterial infection or another specific indication.
When is it urgent?
Severe breathing difficulty, blue lips, collapse, confusion, severe chest pain or rapidly worsening respiratory symptoms need urgent emergency assessment rather than waiting for a routine GP appointment.
