Chronic Headaches: When to Seek Further Medical Evaluation - Neurology

Headache without any apparent cause and examination?


I would like to ask about my headaches, which have been persistent for many years.
Sometimes, they occur without any apparent triggers.
At times, the pain is so severe that it prevents me from sleeping, leading me to take pain relievers.
I have sought medical attention, but tests such as CT scans and EEGs have shown no significant issues.
Occasionally, the pain starts on the left side, while other times it begins on the right side, so it varies.
The doctor mentioned that this is not a cause for concern.
However, recently, I have started experiencing pain primarily on the right side, which sometimes feels sharp and at other times has a throbbing sensation.
There are also instances where I experience nausea and vomiting.
I'm unsure if I should seek further evaluation.
Would it be more effective to undergo testing during an episode of severe pain? I have previously had tests done when I was not experiencing pain; could this have affected the results? Thank you.

Dear Hsi-Hsien, it is unnecessary to conduct tests when experiencing pain, as it may sometimes introduce confounding factors.
The decision to perform tests depends on the specific circumstances and the type of tests being considered.
If no results are found from the headache evaluation, it may be worth trying a course of medication for a period of time before reassessing.

Chronic headaches can be a complex and frustrating condition, especially when they have persisted for many years. Your description of experiencing headaches without clear triggers, along with the variability in pain location and intensity, suggests that you may be dealing with a type of primary headache disorder, such as migraines or tension-type headaches. The fact that you have undergone imaging studies like CT scans and EEGs without significant findings is reassuring, but it does not completely rule out the possibility of underlying issues that may require further evaluation.

When considering whether to seek further medical evaluation for chronic headaches, there are several important factors to keep in mind:
1. Frequency and Severity: If your headaches have become more frequent or severe, as you mentioned with the recent episodes starting from the right side and accompanied by nausea, this is a strong indicator that further evaluation may be warranted. Changes in headache patterns can sometimes signal an underlying issue that needs to be addressed.

2. Associated Symptoms: The presence of additional symptoms, such as vomiting, can be concerning. Migraines, for example, are often associated with nausea and vomiting. However, if these symptoms are new or have changed in nature, it is essential to discuss them with your healthcare provider.

3. Response to Treatment: If over-the-counter pain medications are no longer effective in managing your headaches, or if you find yourself relying on them more frequently, this could indicate that your headaches are becoming more difficult to control. It may be time to explore other treatment options, including prescription medications or preventive therapies.

4. Timing of Evaluations: You raised an important point about the timing of your previous evaluations. It is often more challenging to identify the cause of headaches when a patient is not experiencing pain at the time of the examination. If possible, try to schedule an appointment during a headache episode, or keep a detailed headache diary to document the frequency, duration, intensity, and associated symptoms. This information can be invaluable for your healthcare provider in determining the best course of action.

5. Consulting a Specialist: Given the complexity of your symptoms and the duration of your headaches, it may be beneficial to consult a neurologist or a headache specialist. These professionals have specific training in diagnosing and treating headache disorders and can offer more targeted therapies, including preventive medications, lifestyle modifications, and alternative treatments.

6. Lifestyle Factors: Chronic headaches can often be exacerbated by lifestyle factors such as stress, poor sleep, dehydration, and diet. It may be helpful to evaluate your daily habits and make adjustments where necessary. Regular exercise, adequate hydration, and good sleep hygiene can all contribute to reducing headache frequency and severity.

In summary, while your previous evaluations have not revealed any significant issues, the changes in your headache pattern and associated symptoms warrant further investigation. It is crucial to communicate openly with your healthcare provider about your concerns and to advocate for a thorough evaluation. Keeping a headache diary and seeking a consultation with a specialist can provide you with more insight into your condition and help you find effective management strategies. Remember, you do not have to endure chronic headaches alone; there are resources and treatments available to help improve your quality of life.
