Numbness in Hands and Feet: Causes and Solutions

Numbness in the hands and feet?

Hello, Doctor: I previously had no exercise habits and spent a long time sitting in front of the computer.
Since the end of August, I have been experiencing hand numbness, which at one point was so painful that I couldn't sleep.
This lasted for about a week.
During that time, I underwent an electromyography (EMG) test, and the results indicated that it was not carpal tunnel syndrome.
I later consulted a traditional Chinese medicine practitioner who suggested that it might be due to poor heart health and blood circulation.
After taking herbal medicine, my hand numbness has improved significantly, and I have also started jogging.
However, in the past few days, I have begun to experience a slight numbness in the soles of my feet, which sometimes extends to my calves.
Occasionally, I also feel a cooling sensation, and sometimes only one foot is numb, while at other times both feet are affected.
The numbness tends to intensify when lying down or sitting, and it has slightly impacted my sleep.
Aside from this, my eating, drinking, and bowel movements are normal, and my weight has not fluctuated significantly.
However, the intermittent numbness in my hands and feet is somewhat concerning, and I am unsure which specialty to consult to clarify the cause.
I would appreciate your guidance.
Thank you!

Hello! Based on your description, I recommend that you visit a rehabilitation specialist.
Please observe whether the area of numbness has a specific distribution, its duration, any factors that exacerbate or alleviate it, and whether certain positions trigger it.
This information can be helpful for the treating physician's assessment.
Thank you for your inquiry, and I wish you a speedy recovery!

More Info

Numbness in the hands and feet can be a perplexing and uncomfortable experience, often leading to concerns about underlying health issues. Based on your description, it seems that you have already taken some proactive steps by undergoing an electromyography (EMG) test, which ruled out carpal tunnel syndrome, and you have sought alternative treatments. However, the persistence of numbness and tingling sensations in your feet, particularly after starting a new exercise routine, warrants further exploration.

Possible Causes of Numbness
1. Nerve Compression or Entrapment: While your EMG ruled out carpal tunnel syndrome, other forms of nerve compression could be at play. For instance, conditions like sciatica, where the sciatic nerve is compressed, can lead to numbness in the legs and feet. Similarly, issues in the lumbar spine, such as herniated discs, can also cause radiating numbness.

2. Circulatory Issues: You mentioned that a traditional Chinese medicine practitioner suggested that poor blood circulation might be contributing to your symptoms. Conditions such as peripheral artery disease (PAD) can lead to reduced blood flow to the extremities, causing numbness and cold sensations.
3. Diabetes: Although you did not mention a diabetes diagnosis, it is worth noting that diabetic neuropathy is a common cause of numbness in the hands and feet. If you have risk factors for diabetes, such as obesity or a family history, it might be prudent to check your blood sugar levels.

4. Vitamin Deficiencies: Deficiencies in vitamins, particularly B vitamins (like B12), can lead to neuropathy and numbness. A blood test can help determine if you are deficient in any essential nutrients.

5. Anxiety and Stress: Psychological factors can also manifest physically. Anxiety can lead to hyperventilation and changes in blood flow, which may cause numbness or tingling sensations.

6. Multiple Sclerosis (MS): Although less common, MS can present with numbness and tingling as early symptoms. If you experience other neurological symptoms, such as weakness, vision changes, or coordination issues, it would be wise to consult a neurologist.

Recommendations for Further Evaluation
Given your symptoms and their impact on your daily life, it would be advisable to consult a neurologist. They can perform a thorough neurological examination and may recommend additional tests, such as:
- MRI of the spine: To check for any structural issues that might be compressing nerves.

- Blood tests: To evaluate for diabetes, vitamin deficiencies, and other metabolic conditions.

- Nerve conduction studies: To assess the function of your peripheral nerves.

Management Strategies
1. Physical Therapy: Engaging in physical therapy can help strengthen the muscles around the affected nerves and improve circulation.

2. Lifestyle Modifications: Continuing with your running and incorporating stretching and strengthening exercises can enhance blood flow and nerve health.
3. Dietary Adjustments: Ensure you are consuming a balanced diet rich in vitamins and minerals. If necessary, consider supplements after consulting with a healthcare provider.

4. Stress Management: Techniques such as mindfulness, yoga, or cognitive behavioral therapy can help manage anxiety, which may alleviate some of your symptoms.

5. Regular Monitoring: Keep track of your symptoms, noting any changes or patterns, and communicate these with your healthcare provider.

In conclusion, while numbness in the hands and feet can arise from various causes, a comprehensive evaluation by a specialist is essential to determine the underlying issue and appropriate treatment. Your proactive approach to health, including seeking medical advice and engaging in physical activity, is commendable and will serve you well in managing your symptoms.
