Hello, I have studied your case. There is possibility of migraine. Migraine usually involves half part of your head and associated with nausea. Pain is severe and aggravated by triggering factors like irritant smell, travelling. After clinical examination, medications for migraine like sumatriptans can be started consulting your doctor. For nausea you can take anti emetic like ondansetran. Lifestyle Modifications will help to reduce headache episodes - Proper nutrition - Regular physical activity - Adequate sleep - Stress reduction strategies • Identify and avoid triggers (e.g., tobacco smoke, strong odours, or sprays). • Address workplace ergonomics.
