Experiencing tingling in your hands is common and can happen to anyone. While many factors contribute to tingling and numbness in the hands and feet, some cases are harmless and tend to resolve on their own. However, when accompanied by other symptoms, it’s crucial to consult a doctor as it might point to a more serious health issue.

Causes of Tingling Hands

Tingling, medically known as paresthesia, is described as a sensation similar to being pricked by a needle or bitten by an ant. This can affect both the hands and feet, usually subsiding within a few minutes after adjusting the position.

Typically, tingling occurs due to poor blood circulation. Prolonged sitting or repetitive motions like typing, writing, or cutting can trigger this condition. However, if the tingling persists beyond a few minutes or occurs frequently without a clear cause, it could be a sign of an underlying health condition.

Common health issues associated with tingling include:

Pinched Nerves

When nerves are compressed, tingling or numbness can occur. For instance, sleeping with your hand pressed for too long may lead to discomfort and tingling. A pinched nerve can also be the result of injury, inflammation, or even growths such as tumors putting pressure on the nerve.

Nerve Damage

Chronic or recurring tingling that did not subside in a short time might indicate nerve damage. This symptom can stem from conditions like diabetes, metabolic disorders, or injuries. Damage to the nerves outside the brain and spinal cord can also lead to persistent tingling.

Carpal Tunnel Syndrome

Carpal tunnel syndrome occurs when the median nerve, responsible for finger movement, becomes compressed. Swelling in the wrist’s nerves or tendons can lead to pressure on the median nerve, causing tingling. People at risk include pregnant women, office workers using computers frequently, individuals who handle tools like hammers and drills, and those with a family history of carpal tunnel syndrome.  

Effects of Alcohol Consumption

Excessive alcohol intake can disrupt nutrient absorption, especially vitamin B. Over time, this deficiency can result in conditions like beriberi and Wernicke-Korsakoff syndrome, which manifest as tingling in the hands. 

Vitamin B-12 Deficiency

Lack of vitamin B12 can affect the nervous system, leading to symptoms like numbness and tingling. Other signs of deficiency may include irritability, depression, nausea, vomiting, and diarrhea. Those at risk include individuals who don’t consume vitamin B12-rich foods like eggs, beef liver, or red meat, or those suffering from conditions such as gastritis, anemia, or digestive disorders.

When Should You Seek Medical Advice?

Although tingling is often harmless, persistent tingling that disrupts daily life should prompt a visit to the doctor. Immediate medical attention is necessary if tingling is accompanied by other symptoms, such as:

• Changes in speech, vision, or breathing
• Tingling throughout the limbs or other body parts
• Chest numbness or paralysis
• Loss of bladder control
• Confusion or loss of consciousness
• Tingling spreading to areas like the thighs, buttocks, or genital region

In some cases, tingling could indicate serious conditions like a heart attack or stroke. If the symptoms seem unusual, consult a doctor right away for appropriate treatment. You can also utilize the consultation feature available on the Ai Care app, accessible through the App Store or Play Store.
