Numbness in all four limbs?

Hello, I have a question! My hands and feet often feel numb, and the timing and location of these episodes are quite irregular, but they have been occurring frequently lately.
Last month, it was only occasional, but recently, it happens quite often, mostly in my arms, calves, and fingers.
I also frequently experience dizziness, weakness in my legs and arms, and the dizziness has been becoming more common.
Sometimes, my vision suddenly goes black, but it usually returns after about 1 to 2 minutes.
The frequency of these episodes is about once every 1 to 2 days, and I have noticed a significant decline in my vision.
During an initial examination, the doctor suggested that there might be an issue with my thyroid, as there are cases of thyroid problems in my family.
However, after blood tests, my liver function, thyroid levels, and red blood cell count were normal, with only an abnormal white blood cell count.
The doctor advised me to continue monitoring my condition.
What should I do about my situation? Is there anything I can pay attention to on my own?

Based on your description: The symptoms of dizziness and numbness you mentioned are more likely caused by syncope or hyperventilation.
A rapid drop in blood pressure or vasoconstriction can lead to decreased cerebral blood flow, which may trigger symptoms such as dizziness or blurred vision.
Syncope is more likely to occur when a person is standing, as this position results in the least cerebral blood flow and increased cardiac output.
However, when cerebral blood flow decreases suddenly, it can lead to fainting due to the inability to respond in time.
The likelihood of this happening while sitting is lower, and it is almost nonexistent when lying down.
Prior to losing consciousness, there may be prodromal symptoms such as nausea, yawning, dizziness, a feeling of warmth, sweating, and cold extremities.
After fainting, the person may appear pale, have cold skin, relaxed muscles, a weak pulse, and remain motionless when lying down.
If you frequently experience these symptoms, do not force yourself to stand; it is advisable to sit down or squat quickly to avoid head injuries from falling.
Regarding hyperventilation, it may cause numbness in the mouth and extremities; I recommend discussing evaluation and treatment with a neurologist.
Wishing you good health and safety.
Best regards, Taoyuan Medical Center, Neurology Department.

More Info

Numbness in the limbs, particularly in the arms, legs, and fingers, can be a concerning symptom, especially when it occurs frequently and is accompanied by other issues such as dizziness and visual disturbances. Your description indicates that this has become a recurrent problem, which warrants a thorough evaluation and understanding of potential underlying causes.

Possible Causes of Numbness
1. Nerve Compression or Injury: Conditions such as carpal tunnel syndrome, herniated discs, or sciatica can compress nerves, leading to numbness and tingling sensations. These conditions often arise from repetitive motions, poor posture, or injuries.

2. Circulatory Issues: Poor circulation can lead to numbness, particularly if blood flow is restricted due to conditions like peripheral artery disease or even temporary positions that compress blood vessels.

3. Vitamin Deficiencies: Deficiencies in vitamins such as B12, B1, and B6 can lead to neurological symptoms, including numbness and tingling. A balanced diet is crucial for maintaining nerve health.

4. Thyroid Disorders: As you mentioned, thyroid issues can lead to various symptoms, including numbness. While your initial tests showed normal thyroid function, it may be worth monitoring this if there is a family history of thyroid disease.

5. Anxiety and Stress: Psychological factors can also manifest physically. Anxiety can lead to hyperventilation, which may cause dizziness and tingling sensations in the extremities.

6. Multiple Sclerosis (MS): Although less common, MS can present with numbness and visual disturbances. This is a more serious condition that requires immediate medical attention.

Self-Care Tips
While it is essential to follow up with your healthcare provider for further evaluation, there are some self-care strategies you can implement to help manage your symptoms:
1. Posture Awareness: Maintain good posture, especially if you spend long hours sitting or working at a desk. Ergonomic adjustments can help reduce nerve compression.

2. Regular Exercise: Engage in regular physical activity to improve circulation and strengthen muscles. Focus on low-impact exercises like walking, swimming, or cycling, which can be easier on the joints.

3. Stretching and Strengthening: Incorporate stretching exercises to relieve tension in the muscles and improve flexibility. Strengthening exercises can help support the nerves and improve overall function.

4. Hydration and Nutrition: Ensure you are well-hydrated and consume a balanced diet rich in vitamins and minerals. Foods high in B vitamins, omega-3 fatty acids, and antioxidants can be beneficial for nerve health.

5. Stress Management: Practice relaxation techniques such as deep breathing, meditation, or yoga to help manage stress levels, which can exacerbate symptoms.

6. Monitor Symptoms: Keep a journal of your symptoms, noting when they occur, their duration, and any potential triggers. This information can be valuable for your healthcare provider in diagnosing the issue.

7. Follow-Up Testing: Since your white blood cell count was abnormal, it is crucial to follow up with your doctor for further testing to rule out any underlying infections or autoimmune conditions.

Conclusion
Given the complexity of your symptoms and the potential for various underlying causes, it is essential to continue working closely with your healthcare provider. They may recommend further testing, such as imaging studies or nerve conduction studies, to pinpoint the cause of your numbness and dizziness. In the meantime, implementing the self-care strategies mentioned above can help manage your symptoms and improve your overall well-being. Always consult your doctor before starting any new treatment or exercise regimen, especially given your medical history and current symptoms.
