What disease is it when you cannot feel pain?

Answer:
leprosy - Signs and symptoms : Skin lesions are the primary external sign.[3] Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs and eyes. Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb and/or diseased as a result of the disease. (wikipedia)

Stroke - signs and symptoms: Sudden numbness, tingling, weakness, or paralysis in your face, arm, or leg, especially on only one side of your body.

bels palsy - numbness of one side of the face

Guillain-Barré syndrome (GBS) - Loss of pain and temperature sensation is usually mild. In fact, pain is a common symptom in GBS, presenting as deep aching pain, usually in the weakened muscles, which patients compare to the pain from overexercising. These pains are self-limited and should be treated with standard analgesics. Bladder dysfunction may occur in severe cases but should be transient. If severe, spinal cord disorder should be suspected.
