Why does the surface of the back of the head sometimes feel刺激感?
Hello, doctor.
Sometimes (this has happened twice with a long interval in between), I suddenly feel a stimulating sensation in my head, as if there is a very sensitive area in my body that is being overstimulated.
I can't remember the circumstances of the first occurrence, but the second time happened today during my nap, when I was in a half-awake, half-asleep state.
It lasted for a while but not long.
What could this issue be?

Hello, based on your description, the symptoms of neuropathic pain differ from typical pain following tissue injury, including sensations such as tingling, stabbing, electric shock, tearing, burning, coldness, numbness, and itching, which may sometimes be accompanied by varying degrees of sensory abnormalities.
The location of your symptoms at the back of the head may indicate irritation of the cervical nerve's dorsal root ganglion.
It is advisable for you to consult a neurologist to discuss examination and treatment options.
Wishing you good health and peace.

More Info
The occasional stimulating sensations you are experiencing in the back of your head can be quite perplexing and may stem from a variety of underlying causes. Based on your description, it appears that these sensations occur sporadically and are characterized by a feeling of heightened sensitivity or stimulation in that specific area. This type of sensation can be associated with several neurological and physiological factors.
One possible explanation for these sensations is related to nerve irritation or compression. The back of the head is home to several important nerves, including the occipital nerves, which can become irritated due to muscle tension, poor posture, or previous injuries. If you have a history of trauma to the head, such as the strong impact you mentioned from your childhood, it is conceivable that this could lead to lingering effects, including nerve sensitivity or irritation.
Another potential cause could be related to tension-type headaches. These headaches often manifest as a sensation of tightness or pressure in the head and can be accompanied by sensitivity in specific areas. Stress, anxiety, and muscle tension in the neck and shoulders can exacerbate these symptoms, leading to the sensations you describe. The fact that you experienced this sensation while in a semi-conscious state during a nap may suggest that your body was in a relaxed state, which can sometimes lead to the awareness of underlying tension or irritation.
Additionally, it is worth considering the possibility of a phenomenon known as "paresthesia," which refers to abnormal sensations such as tingling, prickling, or a feeling of stimulation. This can occur due to various reasons, including nerve compression, inflammation, or even anxiety. If you are experiencing heightened anxiety or stress, this could also contribute to the sensations you are feeling.
Given the complexity of your symptoms and their potential connection to previous head trauma, it is advisable to consult a neurologist or a healthcare professional specializing in neurology. They can conduct a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly imaging studies such as an MRI or CT scan to rule out any serious underlying conditions.
In the meantime, there are several strategies you can employ to help manage your symptoms. Practicing relaxation techniques such as deep breathing, meditation, or gentle yoga can help reduce muscle tension and alleviate stress. Additionally, maintaining good posture, especially if you spend long hours sitting or working at a desk, can help prevent tension from building up in the neck and shoulders.
If you notice that certain activities or positions exacerbate your symptoms, it may be beneficial to modify your routine to avoid those triggers. Keeping a symptom diary can also be helpful in identifying patterns or specific factors that may contribute to your sensations.
In summary, while occasional stimulating sensations in the back of the head can be concerning, they are often related to nerve irritation, tension, or anxiety. A thorough evaluation by a healthcare professional is essential to determine the underlying cause and develop an appropriate treatment plan. In the meantime, focusing on relaxation techniques and maintaining good posture may provide some relief.
