Nerve Damage: Causes of Tingling and Weakness in Limbs

Mild numbness in the hands and feet to complete numbness in the limbs?

Hello Doctor: I have been experiencing mild numbness in some of my fingers since the Lunar New Year, which later progressed to a tingling sensation in all my fingers and toes.
At times, my entire palms and soles feel numb, and I also experience some weakness.
On March 1, I underwent a general health check-up and consulted a doctor.
The doctor mentioned that we would wait for the results of the health examination.
The doctor prescribed the following medications:
- Generic name: 24E040 Nicametate 50mg, Brand name: Sanyl S.C.
TAB.
50mg, Chinese name: 暢力
- Generic name: 23F081 Fludiazepam 0.25mg, Brand name: Era 0.25mg, Chinese name: 癒利舒盼
- Generic name: 27A020 Fursultiamine 50mg, Brand name: Alinamin-F 50mg, Chinese name: 合利他命F50
However, there was no significant improvement.
I am scheduled for a nerve examination on the 9th, and during a follow-up on the 11th, the doctor mentioned nerve damage and inquired about any family medical history, but I am still unclear about the exact condition.
Additionally, the doctor prescribed some out-of-pocket medications:
- Generic name: 27P033 Prednisolone 5mg, Brand name: Compesolon (5mg) Tab, Chinese name: 康速龍錠5毫克
- Generic name: 27H029 Mecobalamine 500mcg, Brand name: Methycobal (500mcg) Cap., Chinese name: 衛采彌可保 P或R 膠囊500毫公絲
- Generic name: 26U014 Ulcerin(Swei) homatropine, Brand name: Swei, Chinese name: 舒胃
- Generic name: 23S066 Chlorzoxazone 200mg, Brand name: Sorin 200mg, Chinese name: 舒力
Yet, there is still no significant improvement.
Last night, after having Western food, I experienced vomiting and diarrhea this morning, but those who ate with me did not have any issues.
I would like to ask what this condition could be.
Some have suggested it might be spinal nerve compression or an endocrine issue.
I am quite troubled and wonder if visiting the emergency room would help resolve this.
I really do not want to waste resources, but I also do not want to waste outpatient fees.
After a month of waiting, could you please provide some insights for reference? Thank you.

Dear Dr.
Huang Ying-Che from the Neurology Department of Tainan Hospital, Executive Yuan Health Department:
Hello,
Based on your age (31 years old) and the symptoms of numbness in your limbs, it appears to be more indicative of polyneuropathy.
However, further inquiry into your medical history, family history, occupation, and recent or long-term medication use is necessary.
This condition should not be related to vomiting or diarrhea unless these symptoms have been persistent or accompanied by abdominal pain.
Please return to your neurologist for further evaluation.
Wishing you good health and all the best!
Sincerely,
The Psychiatry Department, Tainan Hospital, Executive Yuan Health Department

More Info

Nerve damage can manifest in various ways, including tingling sensations, weakness in the limbs, and even numbness. The symptoms you are experiencing, such as the tingling in your fingers and toes, as well as the weakness in your hands and feet, can be indicative of peripheral neuropathy or other neurological conditions. Understanding the underlying causes of these symptoms is crucial for effective management and treatment.

Possible Causes of Nerve Damage
1. Trauma or Injury: Physical injuries, such as fractures or dislocations, can lead to nerve compression or damage. If you have had any recent injuries or accidents, this could be a contributing factor.

2. Diabetes: Diabetic neuropathy is a common complication of diabetes, where high blood sugar levels damage nerves over time. If you have a history of diabetes or elevated blood sugar levels, this could be a potential cause.

3. Vitamin Deficiencies: Deficiencies in vitamins, particularly B vitamins (like B12), can lead to nerve damage. The medications you mentioned, such as Mecobalamine (a form of B12), are often prescribed to address such deficiencies.

4. Autoimmune Diseases: Conditions like Guillain-Barré syndrome or multiple sclerosis can cause nerve damage and lead to symptoms like tingling and weakness.

5. Infections: Certain infections, such as Lyme disease or shingles, can also affect the nerves.

6. Toxins and Medications: Exposure to certain toxins or the side effects of medications can lead to nerve damage. If you have recently started any new medications, it is worth discussing with your doctor.

7. Circulatory Issues: Poor circulation can lead to nerve damage as well. Conditions that affect blood flow, such as peripheral artery disease, can cause symptoms similar to what you are experiencing.

Diagnostic Approach
Given the complexity of your symptoms and the lack of improvement with initial treatments, further diagnostic evaluation is warranted. Here are some steps you might consider:
1. Neurological Examination: A thorough neurological exam can help identify the specific nerves affected and the extent of the damage.

2. Electromyography (EMG) and Nerve Conduction Studies: These tests can assess the electrical activity of muscles and the speed of nerve conduction, helping to pinpoint the location and severity of nerve damage.

3. Blood Tests: Comprehensive blood tests can help identify vitamin deficiencies, diabetes, thyroid issues, and autoimmune markers.

4. Imaging Studies: MRI or CT scans can help visualize any structural issues, such as herniated discs or spinal stenosis, that may be compressing nerves.

Treatment Options
Treatment will depend on the underlying cause of the nerve damage. Here are some common approaches:
1. Medications: Depending on the diagnosis, medications such as corticosteroids (like Prednisolone) may be prescribed to reduce inflammation and swelling around the nerves. Pain relievers and neuropathic pain medications may also be considered.

2. Physical Therapy: Engaging in physical therapy can help improve strength and mobility, as well as reduce symptoms.

3. Nutritional Support: If vitamin deficiencies are identified, dietary changes or supplements may be necessary.

4. Lifestyle Modifications: Managing underlying conditions, such as diabetes, through diet and exercise can help prevent further nerve damage.

5. Alternative Therapies: Some patients find relief through acupuncture, chiropractic care, or other alternative therapies.

When to Seek Immediate Care
If your symptoms worsen or if you experience new symptoms such as severe pain, loss of bladder or bowel control, or significant weakness, it is essential to seek immediate medical attention. Visiting the emergency room may be appropriate if you feel your condition is urgent.

In conclusion, while the symptoms you are experiencing can be distressing, a comprehensive evaluation by a healthcare professional is crucial to determine the underlying cause and appropriate treatment. Do not hesitate to seek further medical advice, as timely intervention can significantly improve outcomes.
