If your thighs tingle during walks, you may suffer from meralgia paresthetica. This condition causes tingling in the thigh, buttock or groin area after engagement in activities that activate the thigh or quadricep muscles. Meralgia paresthetica causes the nerves in your outer thigh to compress. In severe cases, the pinching sensation may turn into sharp, shooting pains in the thigh.
Causes
Thigh trauma, tight clothing, obesity, strenuous workouts and restricted blood flow to the thigh or quadriceps can lead to meralgia paresthetica. Workouts that put excessive pressure on quadricep muscles, such as lunges and squats, may cause nerve damage when done excessively. Surgery in the thigh area also can lead to pinched nerves. High blood pressure and diabetes are illnesses that restrict blood flow, which can cause severe nerve pressure and eventual damage.
Symptoms
Aside from a tingling sensation during walks, you also may feel a burning sensation or numbness in the thighs. Firm pressure or a light touch can activate the tingling. The sensation will either remain in the thigh area or shoot across the groin and buttocks. The tingling, numbness and burning occurs on the outer or lateral part of your thigh. The symptoms intensify after walking, jogging or standing in one position for a long period.
Diagnosing Meralgia Paresthetica
Physicians use X-rays and CT scans to diagnose meralgia paresthetica. Before performing these procedures, doctors generally ask about recent surgeries, injuries or activities that may indicate nerve damage to your thigh. Nerve conduction studies, which evaluate sensory and motor function, detect mild and severe cases of meralgia paresthetica. Bone scans also can detect bone abnormalities that cause pinched nerves.
Treatment and Prevention
Over-the-counter painkillers containing ibuprofen can temporarily relieve the pain associated with meralgia paresthetica. Weight loss, loose-fitting clothes and comfortable low-heeled shoes can ease discomfort as well. In extreme cases, your doctor may suggest corticosteroid injections, which reduce nerve inflammation and relieve pain. Nerve decompression surgery is an option for those experiencing severe pain and symptoms.
