You should seek medical attention if headaches are severe, frequent, worsening, or different from your usual pattern, or if they are accompanied by symptoms such as fever, vomiting, vision changes, weakness, numbness, dizziness, speech difficulties, confusion, seizures, or occur after a head injury. These warning signs may indicate an underlying condition that requires prompt evaluation, and early medical assessment helps prevent complications.

Headaches can be triggered by stress, dehydration, poor sleep, hormonal changes, eye strain, and certain foods or drinks. They can also be a sign of an underlying medical condition. To help prevent headaches, stay hydrated, maintain a regular sleep schedule, manage stress through relaxation or exercise, limit caffeine and alcohol, and avoid foods that seem to trigger them. Frequent or severe headaches should be evaluated by a doctor to identify the cause and receive proper treatment.

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.

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.

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.
