It sounds like you may be experiencing a severe sinus headache due to frontal sinusitis, which can cause pressure, pain, and a feeling of fullness in the forehead. Rest, stay hydrated, and use steam inhalation to help clear the sinuses. Over-the-counter pain relievers may ease discomfort. If the headache is very severe or persistent, see a doctor promptly.

Your symptoms?specifically the recurrent pain, nausea, light sensitivity, and appetite loss?are highly characteristic of migraines, though tension or neck-related headaches can also contribute to back-of-the-head discomfort. For a clear diagnosis, I recommend keeping a detailed headache diary to track your triggers and symptoms, then discussing these patterns with a healthcare provider. They can tailor a management plan for you, which may involve generic acute treatments like triptans, preventive strategies, and lifestyle adjustments.

Headaches are usually harmless, but sudden, severe, or progressively worsening headaches, especially with neurological symptoms, vision changes, fever, or neck stiffness, require urgent medical attention. Avoid self-medicating with strong painkillers without medical advice, as it may mask serious conditions.

What you're describing?pain starting at the back of your head and radiating to your eye?often points to occipital neuralgia or a migraine variant. Occipital neuralgia occurs when the nerves traveling from your neck to your scalp get irritated or compressed. For relief, try applying warm compresses to your neck, gentle stretching, and over-the-counter pain relievers like ibuprofen or acetaminophen. Because these headaches last up to three days, please consult a healthcare professional. They can offer a precise diagnosis and discuss targeted options like physical therapy or prescription treatments to help you feel much better.

I understand how concerning these worsening headaches and eye pain must be. A brain MRI is very helpful here to rule out any structural causes for your unilateral pain and provide peace of mind. Your borderline ANA of 1:80 is quite common and often harmless. However, because of your eye symptoms, your doctor may want to rule out autoimmune conditions like Sj?gren's syndrome, which is where a lip biopsy can sometimes be useful. These tests are proactive steps to help us find clear answers. I recommend discussing these options with your doctor to see if they are the right next steps for you.

Since you have had severe headaches for 8 years with anxiety and a feeling of pressure in the head, it is important to see a doctor or neurologist for a proper evaluation. Long-term headaches can have many causes, like migraine, tension, sinus issues, or other neurological conditions, and the right treatment depends on the cause. A doctor can recommend safe medications, lifestyle changes, and tests to find relief.
