Pharyngitis affects the pharynx, while laryngitis affects the larynx and vocal folds. Sore throat and painful swallowing may dominate pharyngitis; hoarseness may dominate laryngitis. They can occur together.
Viruses are common causes; vocal strain and irritants also contribute to laryngitis. Symptoms overlap, so self-diagnosis is unreliable. Fluids and appropriate voice rest may help, but antibiotics are not routine for either condition. Persistent voice change may warrant laryngoscopy. Breathing difficulty, noisy breathing or inability to swallow saliva requires urgent assessment.
Assessment covers the mouth, throat and neck; endoscopy or tests are selected when needed. Antibiotics, acid-suppressing medicines and surgery require an appropriate diagnosis. Avoiding smoke and maintaining suitable hydration may reduce irritation.
Difficulty breathing or inability to swallow saliva is an emergency. Persistent one-sided pain, a neck lump, voice changes or unexplained weight loss should be assessed promptly.
This information does not replace an individual consultation. Diagnosis and treatment depend on a medical assessment.
