While sensory symptoms can be aggravating, they are not life-threatening and can usually be managed or treated. These symptoms are very common in MS and include feelings of burning, aching, and tingling discomfort most often in the limbs.

Paresthesias

Paresthesias, which are characterized by tingling, numbness, itching, burning, or stabbing or tearing pain, occur in up to 55 percent of people with MS and may be the earliest MS symptom.

Lhermitte's Sign

Lhermitte's sign describes the electric buzzing sensations in the limbs and torso brought on by movement of the neck and is most often triggered by lowering the chin to touch the chest. Lhermitte's is an indicator of lesions in the cervical spine. Movement of the neck causes the damaged nerves to be stretched and send erroneous signals to the brain.

Trigeminal Neuralgia (TN)

Trigeminal neuralgia is an acute, shocklike pain in the regions of the face served by the trigeminal nerve. This nerve serves three areas of the face: the forehead, cheek, and jaw. TN can affect some or all of these areas (usually on one side of the face) and can be triggered by a number of factors, including crying, laughing, or brushing one's teeth.
