I'm sorry to hear about the persistent right-sided headache and eye pain you've been experiencing for several years. Chronic headaches and eye pain can have various causes, including migraine, cluster headaches, sinus issues, or other neurological conditions. Because your symptoms have lasted this long, it is important to have a thorough evaluation by a neurologist or an eye specialist (ophthalmologist) to determine the exact cause and appropriate treatment.

In the meantime, avoid triggers such as stress, certain foods, or excessive screen time, and maintain good hydration and regular sleep patterns. Over-the-counter pain relief may help temporarily, but it is not a long-term solution.

Please consult a neurologist or ophthalmologist promptly for a detailed assessment and personalized treatment plan. If your symptoms worsen or you experience vision changes, sudden weakness, or confusion, seek emergency medical care immediately.To narrow down potential causes, we will need some more information.I understand you've been dealing with a right-sided headache and pain in your right eye for quite some time. To help me understand your situation better, could you please tell me your age and gender?
