What does tingling and numbness in your upper leg mean?

Tingling and numbness in the upper leg can indicate nerve compression or irritation, often caused by conditions such as sciatica, herniated discs, or peripheral neuropathy. It may also result from poor circulation or prolonged pressure on the nerves, such as sitting in one position for too long. If these symptoms persist or are accompanied by pain, weakness, or other concerning signs, it's important to consult a healthcare professional for proper evaluation and diagnosis.
