Left leg numbness can be caused by localized lesions, metabolic diseases, and other factors. Localized conditions such as trauma, excessive fatigue, infection, or cold exposure may affect microcirculation to some extent. It is important to keep the area warm in daily life. Peripheral neuropathy resulting from metabolic disorders, such as diabetes, can also lead to numbness. Additionally, sciatic nerve lesions—when the sciatic nerve is irritated or compressed—can cause numbness in the left leg.
