I'm sorry to hear about the radiating pain you're experiencing on the top right of your head and neck, especially after recently being treated for dengue fever. This kind of pain could be related to several factors, including muscle strain, nerve irritation, or complications following an infection like dengue.

Here are some important points and steps you can take:

• Monitor Symptoms: If the pain is severe, worsening, or accompanied by other symptoms such as fever, neck stiffness, weakness, numbness, or changes in vision or consciousness, seek immediate medical attention.

• Pain Management: Over-the-counter pain relievers such as non-steroidal anti-inflammatory drugs (NSAIDs) may help reduce pain and inflammation. However, since you recently had dengue fever, it is crucial to avoid medications that can increase bleeding risk, such as aspirin or certain NSAIDs, without consulting a doctor.

• Rest and Support: Ensure adequate rest and avoid activities that strain your neck. Applying warm or cold compresses may provide some relief.

• Follow-Up Care: Given your recent dengue infection and current symptoms, it is important to consult a neurologist or an infectious disease specialist. They can evaluate for any neurological complications or other causes of your pain and recommend appropriate investigations or treatments.

If your pain worsens or you develop new symptoms, do not hesitate to seek emergency care immediately.
