Feeling pins and needles in your feet, also known as paresthesia, is a common sensation with various causes. Sometimes it's harmless, but other times it signals an underlying health issue.
Common Causes of Pins and Needles in Feet
-
Prolonged Pressure: Simply sitting or standing in one position for too long can restrict blood flow to your nerves, causing that familiar tingling sensation. This is usually temporary and resolves quickly once you change position. [Source: Multiple articles mentioned tingling as a result of prolonged pressure/poor circulation]

Peripheral Neuropathy: This condition involves nerve damage, often affecting the extremities. Diabetes and kidney failure are two conditions that can lead to peripheral neuropathy, causing symptoms like burning or tingling, described as "pins and needles."

Other Underlying Health Conditions: Besides diabetes and kidney failure, numerous other health issues can manifest with tingling feet. These can include vitamin deficiencies, nerve compression from arthritis or injury, and various other medical conditions. [Source: Cedars-Sinai, Health.com, WebMD]
Understanding the Sensation
The "pins and needles" feeling happens because of disrupted nerve function. When blood flow or nerve function is temporarily impaired, you experience this tingling or prickling. This often feels like a pricking, tingling, or numbness sensation. [Source: Better Health Channel, NHS]
When to See a Doctor
While often benign, persistent or severe tingling in your feet warrants medical attention. It's crucial to consult a doctor to determine the underlying cause, especially if accompanied by other symptoms like numbness, weakness, or pain. Early diagnosis and treatment are vital for managing conditions like peripheral neuropathy.
