Headaches can be a complex and multifaceted issue, often influenced by various factors including past injuries, stress, and neurological conditions. Your concern about the relationship between your headaches and a previous head injury is valid, and it's important to explore this connection further.

Firstly, it's essential to understand that the brain itself does not have pain receptors, which means it cannot feel pain directly. However, headaches can arise from various structures surrounding the brain, including blood vessels, nerves, and the meninges (the protective membranes covering the brain). When these structures are irritated or inflamed, they can trigger pain signals that manifest as headaches.

In your case, the fact that you experienced a head injury two years ago could potentially be related to your current headaches. Although you mentioned that you were evaluated by a doctor after the injury and found to be fine, it's possible that there could be lingering effects that were not immediately apparent. For instance, post-concussion syndrome can occur after a head injury, leading to persistent headaches, dizziness, and cognitive difficulties. This syndrome can develop even if the initial injury seemed minor.

The location of your headache, specifically in the right posterior part of your head, could suggest several possibilities. Tension-type headaches, which are often caused by muscle tension in the neck and scalp, can lead to pain that feels like a tight band around the head. On the other hand, if the pain is more localized and pulsating, it might indicate a migraine or a cluster headache, both of which can have neurological components.

Moreover, the timing of your headaches—starting a few months ago—could suggest that they are related to stress or changes in your lifestyle, especially if you have been experiencing increased anxiety or tension. Stress is a well-known trigger for headaches, and it can exacerbate underlying conditions.
It's also worth considering the possibility of cervicogenic headaches, which originate from issues in the cervical spine (neck) but are felt in the head. If your neck was affected during the injury, it could lead to referred pain in the head.

Given your history and the persistence of your symptoms, it would be prudent to consult a neurologist or a headache specialist. They can conduct a thorough evaluation, which may include imaging studies like an MRI or CT scan, to rule out any structural issues or complications from your previous injury. Additionally, they can help determine the specific type of headache you are experiencing and recommend appropriate treatment options.

In the meantime, consider keeping a headache diary to track the frequency, duration, and intensity of your headaches, as well as any potential triggers. This information can be invaluable for your healthcare provider in diagnosing and managing your condition.

In summary, while your previous head injury may not have caused immediate issues, it could be contributing to your current headaches. Understanding the underlying causes and seeking appropriate medical advice is crucial for effective management and relief from your symptoms.
