Initial management focuses on identifying and treating the underlying cause. Lifestyle modifications, over-the-counter medications, and specialist referral may all play a role depending on the severity and etiology.

Seek immediate medical attention if symptoms are sudden, severe, or accompanied by warning signs including high fever, neurological changes, difficulty breathing, or persistent chest pain. Early diagnosis significantly improves outcomes.
