Head Injury from Medical Infrared Device: Recovery Tips and Risks

Hit on the top of the head?

Hello Doctor: Yesterday, I was hit on the top of my head by a medical-grade low-temperature far-infrared device.
When I went from sitting to standing, my head hit the device.
At the moment, I only felt some pain, but today it still hurts.
I do not have nausea or dizziness.
I would like to ask the doctor: 1.
How many days later can I use warm compresses (the far-infrared device temperature is about 40 degrees Celsius) to accelerate recovery? How should I protect myself in the meantime? 2.
I have checked and there were no immediate issues, but there is a possibility of chronic subdural hematoma in the future.
What is the likelihood of this? How can I avoid it? Can daily warm compresses help prevent hematomas?

Hello, based on your description, generally speaking, if there is no loss of consciousness, no anticoagulant use, or obvious local hematoma, head trauma is mostly mild.
However, the following situations should prompt consideration of delayed bleeding and a visit to the emergency room: (1) worsening vision, seeing double (diplopia), or unequal pupil size.
(2) Clear fluid or blood leaking from the ears or nose.
(3) Confusion or abnormal behavior.
(4) Numbness or inability to move limbs.
(5) Localized involuntary movements or seizures.

1.
Can I use warm compresses (with a low far-infrared device at about 40 degrees Celsius) a few days later to speed up recovery? How should I protect myself during these days?
A: It is generally recommended to use ice packs within the first 48 hours to reduce tissue swelling and alleviate pain.
Heat can be applied after 48 hours.
2.
I have checked and there were no immediate issues, but is there a high possibility of chronic subdural hematoma in the future? How can I avoid it? Can daily warm compresses prevent hematomas?
A: Chronic subdural hematoma typically occurs in the elderly with brain atrophy, long-term alcohol users, epilepsy patients, or those with blood coagulation disorders, including those on anticoagulants.
If you do not have symptoms such as headaches or limb weakness, your risk is relatively low.
It is advisable to consult a neurologist for discussion regarding examination and treatment.
Wishing you good health and peace.

When dealing with a head injury, especially one caused by a medical infrared device, it is crucial to approach recovery with caution and awareness of potential risks. Here are some recovery tips and considerations based on your situation:
1. Initial Care and Observation: After sustaining a head injury, it is essential to monitor your symptoms closely. You mentioned experiencing pain but no nausea or dizziness, which is a positive sign. However, it is important to remain vigilant for any changes in your condition. If you start to experience severe headaches, confusion, vomiting, or any other concerning symptoms, seek medical attention immediately.

2. Using Heat Therapy: Regarding your question about using a low-temperature infrared device for warmth, it is generally advisable to wait at least 48 to 72 hours after the injury before applying heat. This waiting period allows any potential swelling to decrease. Once you start using heat, ensure that the temperature is comfortable and not too hot, as excessive heat can exacerbate swelling or discomfort. Applying heat can help improve blood circulation and promote healing, but it should be done cautiously.

3. Protecting the Injury: During the initial recovery phase, it's important to protect your head from further injury. Avoid activities that could lead to another impact, such as contact sports or vigorous physical activity. If you need to move around, be cautious and consider using protective headgear if you are engaging in any activity that poses a risk of falling or bumping your head again.

4. Long-term Risks: You mentioned concerns about the potential for chronic subdural hematoma (a type of bleeding that can occur between the brain and its outer covering). While the risk of developing this condition after a minor head injury is generally low, it can increase with age or if you have other risk factors such as blood clotting disorders or if you take anticoagulant medications. To minimize risks, maintain a healthy lifestyle, manage any underlying health conditions, and avoid activities that could lead to head trauma.

5. Heat Application and Blood Clots: Daily application of heat may help with discomfort and promote healing, but it does not necessarily prevent the formation of blood clots or hematomas. If you are concerned about blood clots, it is essential to discuss this with your healthcare provider, who may recommend monitoring or additional interventions.

6. Follow-up Care: It is advisable to have a follow-up appointment with your healthcare provider to assess your recovery and discuss any lingering symptoms. They may recommend imaging studies if there are concerns about internal bleeding or other complications.

7. Gradual Return to Activities: As you recover, gradually reintroduce activities into your routine. Start with light activities and increase intensity as tolerated. Listen to your body and avoid pushing through pain.

In summary, while minor head injuries often resolve without complications, it is essential to monitor your symptoms closely and take appropriate precautions during recovery. If you have any doubts or experience new symptoms, do not hesitate to seek medical advice. Your health and safety should always come first.
