Contact your GP practice, dentist, pharmacy or NHS 111 Wales if symptoms are severe, getting worse, or you are worried.
A pharmacist may be able to help
A community pharmacist can give advice about many common mouth and throat problems. In Wales, cold sores, mouth ulcers and sore throat are covered by the NHS Wales Common Ailments Service.
For sore throat and tonsillitis, some pharmacies also offer a Sore Throat Test and Treat service, which can help check whether symptoms are more likely to be caused by a viral or bacterial infection.
