Numbness
Numbness, or the sensation of tingling in the hands or feet, is a common and often bothersome symptom experienced by many individuals. In some instances, it may be temporary, occurring due to nerve compression from awkward hand positions or prolonged sitting. In these cases, the accompanying pain can be sharp but typically resolves once the pressure is relieved, which is common in numerous instances.
However, if the numbness is severe and accompanied by other symptoms such as itching and intense tingling, it is imperative to seek medical attention immediately, as this could indicate a more serious underlying issue within the body.
When to See a Doctor
There are various symptoms associated with numbness that warrant medical evaluation, including:
- Pain
- Itching
- Severe tingling
- Muscle spasms
- Dizziness
- Blurry vision
- General weakness

- Loss of consciousness
- Loss of control over bowel or bladder function

Causes of Numbness in the Feet
The primary cause of numbness remains unknown in approximately 30% of affected individuals. However, it may be related to one or more of the following factors:
- Diabetes: This condition is one of the most prevalent causes of nerve damage, accounting for around 30% of numbness cases. Roughly two-thirds of people with diabetes experience tingling in their feet, with pain intensity varying from mild to severe. For some, this may signal the onset of diabetes.
- Organ-related diseases: Conditions affecting the kidneys, liver, blood vessels, tissues, chronic inflammation, hormonal imbalances, cancers, or benign tumors can harm the nerves.
- Vitamin deficiencies: Vitamins such as B12, B6, B1, and E are essential for nerve health. In some cases, an excess of vitamin B6 may also lead to tingling sensations in the hands and feet.
- Alcohol addiction: Individuals with alcohol dependency often suffer from significant deficiencies in vitamins and minerals due to poor dietary habits, making neuropathy a common consequence of alcohol abuse.
- Toxin exposure: Contact with heavy metals like lead, arsenic, and mercury or certain industrial chemicals and some chemotherapy medications can result in nerve damage.
- Infections: Various infections, including herpes and HIV, can lead to symptoms of numbness.
- Autoimmune diseases: Conditions like lupus and rheumatoid arthritis may contribute to nerve issues.
- Injury: Accidents that exert excessive pressure on the nerves can cause numbness.
- Poor circulation: Reduced blood flow can lead to feelings of tingling or numbness.
- Migraine: Migraines can sometimes manifest with neurological symptoms, including numbness.
- Stroke or heart attacks: Both conditions can present with numbness as a symptom.
Treatment Options for Numbness
The effectiveness of treatment largely hinges on an accurate diagnosis and addressing the root cause of the numbness. If the nerve cells have not been severely damaged, there is a significant chance for regeneration.
While there may not be a specific cure for some types of neuropathy, other symptoms can usually be managed. For example, numbness resulting from diabetes can be controlled by maintaining appropriate blood sugar levels, and vitamin supplements may be necessary to address deficiencies if that is the underlying cause. Other treatment plans will be tailored by medical professionals according to the specific condition causing the numbness.
