Hello, doctor. I would like to ask you some questions?

Hello, doctor.
I have three questions to ask:
1.
When I was 20 years old, I slipped down the stairs and hit the back of my head, resulting in continuous bleeding.
At that moment, I felt dizzy and had a loss of consciousness.
I went to the hospital, where the doctor only shaved the hair around the area and applied pressure to stop the bleeding.
Should I be concerned about any long-term effects now?
2.
When I press on the top of my head towards the back, I experience a feeling of nausea.
Is this a cause for concern?
3.
If I stare at a specific spot without blinking, I start to feel dizzy.
Is this normal? Thank you.

Hello! Thank you for your questions regarding head injuries, nausea, and dizziness. These are important topics in neurology, and I’ll address each of your concerns in detail.

1. Concerns About Past Head Injury: You mentioned that you suffered a head injury at the age of 20 when you fell down the stairs and hit the back of your head, resulting in bleeding and temporary confusion. It’s understandable to be concerned about potential long-term effects from such an injury. Generally, the risk of developing complications from a single, isolated head injury, especially if it was managed appropriately at the time, is relatively low. However, factors such as the severity of the injury, the presence of any loss of consciousness, and subsequent symptoms can influence the risk of long-term effects like cognitive decline or chronic headaches. If you have not experienced any significant issues since then, such as persistent headaches, memory problems, or changes in mood, it is likely that you are not at a heightened risk for dementia or other neurological disorders. Nonetheless, if you have any ongoing symptoms or concerns, it would be wise to consult a neurologist for a thorough evaluation.

2. Nausea When Pressing on the Head: You mentioned experiencing nausea when pressing on the top of your head and the back of your head. This could be related to several factors. One possibility is that pressing on certain areas of the skull can stimulate nerves that may cause discomfort or a nauseous feeling. Additionally, if there is any underlying tension or muscle strain in the neck or scalp, it could contribute to this sensation. However, if this nausea is frequent or accompanied by other symptoms such as severe headaches, visual disturbances, or changes in consciousness, it would be advisable to seek medical attention to rule out any serious conditions.

3. Dizziness from Staring Without Blinking: It is quite common to experience dizziness or discomfort when staring at a fixed point without blinking for an extended period. This can happen because your eyes become fatigued, and the lack of blinking can lead to dryness and irritation, which might trigger a sensation of dizziness. Additionally, focusing intently on one spot can cause your brain to become overstimulated, leading to feelings of lightheadedness. To alleviate this, it’s a good practice to take regular breaks, blink frequently, and shift your gaze to different objects to reduce eye strain.

In summary, while your past head injury may not pose a significant risk if you have been symptom-free, it’s always prudent to monitor your health and consult with a healthcare professional if you have any concerns. The symptoms of nausea when pressing on your head and dizziness from staring are worth discussing with a doctor, especially if they persist or worsen. Neurological health is complex, and individual experiences can vary widely, so personalized medical advice is always the best course of action. Thank you for your questions, and I hope this information helps clarify your concerns!
