### Understanding Tingling in Hands and Feet Tingling in the hands and feet, often described as a 'pins and needles' sensation, is medically known as paresthesia. This can feel like pricks, numbness, or burning under the skin. While it can be a temporary and benign issue, such as when you put pressure on your arm while sleeping or cross your legs for too long, it can also be a sign of more serious conditions. #### Common Causes 1. **Nerve Damage (Peripheral Neuropathy)**: This is the most common cause and can result from diabetes, traumatic injuries, infections, or toxic exposures. About two-thirds of people with diabetes experience some form of nerve damage. 2. **Repetitive Stress Injuries**: Activities that involve repetitive motion can lead to nerve compression. 3. **Infections**: Bacterial or viral infections can damage nerves. 4. **Vitamin Deficiencies**: Lack of certain vitamins can affect nerve health. 5. **Other Diseases**: Conditions like multiple sclerosis or lupus can also cause tingling. #### When to Seek Medical Help If the tingling persists, is severe, or is accompanied by other symptoms like pain, itching, or muscle weakness, it's important to consult a healthcare provider. Early diagnosis and treatment can prevent long-term damage. #### Treatment Options 1. **Medications**: Over-the-counter or prescription medicines can help manage symptoms. 2. **Physical Therapy**: Can help improve mobility and reduce symptoms. 3. **Lifestyle Changes**: Managing underlying conditions like diabetes through diet and exercise can help. 4. **Surgery**: In some cases, surgery may be needed to relieve nerve compression. #### At-Home Care - Avoid repetitive motions that cause tingling. - Maintain a healthy diet to prevent vitamin deficiencies. - Manage chronic conditions effectively. If you experience sudden or severe tingling, or if it is accompanied by other symptoms like a rash or muscle weakness, seek immediate medical attention.
