Awareness of the more uncommon multiple sclerosis symptoms can lead to an earlier diagnosis and appropriate treatment. For instance, experiencing electrical shock sensations when bending the neck forward, known as Lhermitte's sign, may indicate an attack on the cervical spinal cord. Likewise, excruciating bolts of pain across either side of the face, called trigeminal neuralgia, can be caused by a MS relapse. The MS hug, an unfriendly, squeezing sensation around the torso, can respond to muscle relaxants and nerve pain medications. Some MS symptoms, like tingling in legs, only surface when exercising or overheated (Uhthoff's phenomenon).

Vertigo, a spinning sensation, can be a sign of MS, especially when lasting days and accompanied by other symptoms like gait imbalance, facial numbness and double vision. Brainstem attacks may also lead to swallowing issues and shaky vision. While MS bladder issues are commonly addressed, bowel problems, including constipation, urgency, incontinence and trouble evacuating, should not be overlooked. Overcoming stigma is essential to treat sexual dysfunction.
