Catarrh that lasts
The NHS advises seeing a GP if catarrh lasts more than a few weeks. A planner is a way to record questions, not a reason to delay an appointment or a way to confirm a diagnosis.
A cough and urgent symptoms
The NHS advises seeing a GP for a cough lasting more than three weeks. Finding it hard to breathe, chest pain, feeling very unwell or coughing up blood need urgent medical advice. Follow the linked source and seek-help checklist for the appropriate action; do not wait for a weekly review.
UK and US routes
UK readers can contact a GP or NHS 111 for urgent advice; in an emergency call 999. US readers should contact their doctor or urgent care, or call 911 in an emergency. If unsure, contact a healthcare professional rather than relying on this educational article.
