Does leg numbness and tingling mean nerve damage or poor blood circulation?

Leg numbness and tingling can indicate various issues, including nerve damage or poor blood circulation. Nerve damage, often associated with conditions like Diabetes or sciatica, can lead to these sensations due to nerve compression or injury. On the other hand, poor blood circulation can also cause numbness and tingling, often resulting from vascular problems or prolonged pressure on blood vessels. It's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
