I'm experiencing numbness, burning, tingling and sharp pain in my left thigh?

Anatomy. Could involve femoral nerve, an L2-3 radiculopathy, or most likely lateral femoral cutaneous nerve of thigh. Best to discuss with your doctor, consider neurology consultation, and get this addressed.
Pain in thigh. Numbness, burning, tingling and sharp pain all sound like a nerve is involved. This could happen if there was any injury to the back, such as when you move or lift something heavy or it could possibly be the beginning of shingles. Please see your doctor right away for an evaluation.
