Top 4 Numbness in One Thigh Causes

  1. 1.Sciatica

    The sciatic nerve is the largest nerve of the human body, and it runs through the buttock, down the thigh and into the calf, sending information to the muscles in the back of the thigh and leg, as well as the surrounding skin. The sciatic nerve itself is supplied by nerves coming from the spine in the lower back. Sometimes, one of the disks separating the vertebrae (bones of the spine) may bulge out a little bit, putting pressure on one of these nerve roots, causing sciatica, or shooting pain down the sciatic nerve.

    You can safely treat this condition on your own. Over-the-counter pain medications such as ibuprofen (Advil) and aspirin as well as muscle relaxants may help. Some people find applying gentle heat or cold on painful muscles is soothing as well. It is important to stay active! Remaining in bed for too long may cause more inflammation.

  2. 2.Piriformis Syndrome

    Piriformis syndrome is a condition when a muscle spanning the lower spine to the top of the thighbone presses upon the sciatic nerve, causing pain and numbness.

    You should visit your primary care physician, who would perform a physical exam, looking for other possible causes of your symptoms. Treatment involves NSAIDs (Ibuprofen), massage, and physical therapy.

  3. 3.Thigh Nerve Issue (Meralgia Paresthetica)

    Meralgia paresthetica is a nerve condition that causes an area of skin over the upper outer thigh to feel numb, tingly, or painful. This is caused by compression of a nerve known as the lateral cutaneous nerve of the thigh as it passes underneath a tough fibrous ligament known as the inguinal ligament.

    You should visit your primary care physician to confirm the diagnosis and discuss treatment options. Generally, this condition is treated with rest, physical therapy, pain medication, and occasionally corticosteroid injections.

    Rarity:
    Rare
    Top Symptoms:
    hip pain, pain in one thigh, pain in one hip, pain in the outside of the hip, thigh numbness
    Symptoms that never occur with thigh nerve issue (meralgia paresthetica):
    new headache, swollen hip, swollen hips, swelling of one hip, leg swelling, weakness of both legs, leg weakness
    Urgency:
    Primary care doctor
  4. 4.Benign Bony Growth (Osteochondroma)

    An osteochondroma is a non-cancerous growth that usually develops during childhood or adolescence. It is a benign tumor that forms on the surface of a bone near the growth plate.

    You should visit your primary care physician for X-Ray evaluation. In most cases this condition is treated by careful observation over time to make sure the tumor does not grow. Surgery is considered if the osteochondroma causes pain, puts pressure on a nearby nerve or blood vessel, or has a large cap of cartilage.

    Top Symptoms:
    numbness in one arm, numbness in one thigh, swelling of one arm, hip deformity, swollen knee
