Quick Answer. Pain and numbness on either the left or right thigh can be caused by meralgia paresthetica, peripheral neuropathy, multiple sclerosis and lupus, explains Healthgrades. Some other causes include injury, obesity, trauma and tight clothing, notes the American Academy of Orthopaedic Surgeons.
For example, irritated nerves as they pass around the knee joint can cause tingling and numbness in the lower part of the leg. Hernias, such as a femoral hernia in the groin area, can also cause numbness or tingling to the front of the thigh down toward the knee. Even hip arthritis can cause leg pain that extends from the groin down to the knee. Much of the time, differentiating causes of leg pain, tingling, or numbness can be made by just hearing the story of where the pain is in the leg. Physical exam, checking reflexes, nerve stretching, and joint range of motion can also help with the diagnosis.
