Persistent Headaches: Causes and When to Seek Help - Neurology

More Info

Persistent headaches can be a source of significant discomfort and concern, especially when they last for an extended period, such as a month or more. Based on your description, it seems that your headaches are located in the back of your head and at the top, primarily on the left side, and they present as a dull, pressure-like sensation. While you mentioned that these headaches do not severely impact your daily life or sleep, it is still important to understand the potential causes and when to seek further medical evaluation.

There are several types of headaches, and the characteristics you've described could suggest a few possibilities. One common type is tension-type headache, which is often characterized by a dull, aching sensation and a feeling of tightness or pressure across the forehead or back of the head. These headaches can be triggered by stress, anxiety, poor posture, or prolonged periods of sitting, especially if you spend long hours in front of a computer. Given that you mentioned your work involves extended computer use, this could be a contributing factor.

Another possibility is cervicogenic headache, which originates from issues in the cervical spine (the neck) and can refer pain to the head. This type of headache is often associated with neck stiffness or discomfort and can be exacerbated by certain movements or positions.

Migraines are another type of headache that can sometimes present with pressure-like sensations, although they are typically more intense and may be accompanied by other symptoms such as nausea, sensitivity to light, or visual disturbances. However, your description does not strongly indicate a migraine, especially since you mentioned that the pain does not worsen significantly over time.

Since you have already undergone an EEG (electroencephalogram) and found no abnormalities, it is reassuring, but it does not rule out other potential causes. If your headaches persist or worsen, or if you begin to experience additional symptoms such as visual changes, weakness, or neurological deficits, it is crucial to seek further evaluation. A thorough examination by a neurologist may be warranted, and they might recommend imaging studies such as an MRI or CT scan to rule out any structural issues or other underlying conditions.

In terms of management, if your headaches are indeed tension-type or cervicogenic, lifestyle modifications can be beneficial. These may include:
1. Posture Correction: Ensure that your workstation is ergonomically set up to reduce strain on your neck and back.

2. Regular Breaks: Take frequent breaks from screen time to stretch and relax your muscles.

3. Stress Management: Techniques such as mindfulness, yoga, or meditation can help alleviate stress, which may contribute to tension headaches.

4. Hydration and Nutrition: Staying hydrated and maintaining a balanced diet can also play a role in headache prevention.

Over-the-counter pain relievers like acetaminophen or NSAIDs (non-steroidal anti-inflammatory drugs) can be effective for occasional headaches, but relying on them daily is not advisable without consulting a healthcare provider, as it can lead to medication overuse headaches.

In summary, while your symptoms may suggest tension-type headaches or cervicogenic headaches, it is essential to monitor your condition closely. If the headaches persist or change in nature, or if you develop new symptoms, seeking a comprehensive evaluation from a neurologist would be prudent. They can provide a tailored approach to diagnosis and management, ensuring that any underlying issues are addressed appropriately.
