Numbness is the partial or complete loss of sensation in a specific area of the body — most commonly affecting the hands, fingers, arms, legs, or feet. It may feel like your skin has “fallen asleep” and is often accompanied by tingling, prickling, or a pins-and-needles sensation. Some people also experience weakness, burning, or a sense of heaviness in the affected area.
Numbness isn’t a condition on its own — it’s a symptom of something deeper. In most cases, it points to an issue involving nerve irritation, nerve compression, or reduced blood flow to the area. It can be triggered by a range of causes, from a slipped disc or spinal misalignment to conditions like diabetes, poor posture, repetitive strain, or even anxiety. The key to treating numbness lies in identifying and addressing the root cause — not just masking the sensation.
