You may be experiencing symptoms of an allergic reaction. To address the itching and redness, you can take an antihistamine such as Cetirizine (10mg) once daily. For the headache, you can take Acetaminophen (500mg) as needed for pain relief. However, it is important to identify and avoid the trigger causing your symptoms. If the symptoms persist or worsen, please seek medical attention for further evaluation and management.
