MS symptoms are variable and unpredictable. No two people have exactly the same symptoms, and each person’s symptoms can change or fluctuate over time. One person might experience only one or two of the possible symptoms while another person experiences many more.
Explore the list below to find more information about the symptoms you or someone you care about is experiencing. Most of these symptoms can be managed very effectively with medication, rehabilitation and other management strategies. Effective symptom management by an interdisciplinary team of healthcare professionals is one of the key components of comprehensive MS care.

More common symptoms
Fatigue
Occurs in about 80% of people, can significantly interfere with ability to function at home and work, and may be the most prominent symptom in a person who otherwise has minimal activity limitations.Walking (Gait) Difficulties
Related to several factors including weakness, spasticity, loss of balance, sensory deficit and fatigue, and can be helped by physical therapy, assistive therapy and medications.Numbness or Tingling
Numbness of the face, body, or extremities (arms and legs) is often the first symptom experienced by those eventually diagnosed as having MS.Spasticity
Refers to feelings of stiffness and a wide range of involuntary muscle spasms; can occur in any limb, but it is much more common in the legs.Weakness
Weakness in MS, which results from deconditioning of unused muscles or damage to nerves that stimulate muscles, can be managed with rehabilitation strategies.Vision Problems
The first symptom of MS for many people. Onset of blurred vision, poor contrast or color vision, and pain on eye movement can be frightening — and should be evaluated promptly.Dizziness and Vertigo
People with MS may feel off balance or lightheaded, or — much less often — have the sensation that they or their surroundings are spinning (vertigo).Bladder Problems
Bladder dysfunction, which occurs in at least 80% of people with MS, usually can be managed quite successfully through dietary and fluid management, medications, and catheterization.Sexual Problems
Very common in the general population including people with MS. Sexual responses can be affected by damage in the central nervous system, as well by symptoms such as fatigue and spasticity, and by psychological factors.Bowel Problems
Constipation is a particular concern among people with MS, as is loss of control of the bowels. Bowel issues can typically be managed through diet, adequate fluid intake, physical activity and medication.Pain
Pain syndromes are common in MS. In one study, 55% of people with MS had "clinically significant pain" at some time, and almost half had chronic pain.Cognitive Changes
Refers to a range of high-level brain functions affected in 50% of people with MS, including the ability to learn and remember information, organize and problem-solve, focus attention and accurately perceive the environment.Emotional Changes
Can be a reaction to the stresses of living with MS as well as the result of neurologic and immune changes. Bouts of depression, mood swings, irritability, and episodes of uncontrollable laughing and crying pose significant challenges for people with MS and their families.Depression
Studies have suggested that clinical depression — the severest form of depression — is among the most common symptoms of MS. It is more common among people with MS than it is in the general population or in persons with many other chronic, disabling conditions.
Less common symptoms
Speech Problems
Speech problems, including slurring (dysarthria) and loss of volume (dysphonia) occur in approximately 25-40% of people with MS, particularly later in the disease course and during periods of extreme fatigue. Stuttering is occasionally reported as well.Swallowing Problems
Swallowing problems — referred to as dysphagia — result from damage to the nerves controlling the many small muscles in the mouth and throat.Tremor
Tremor, or uncontrollable shaking, can occur in various parts of the body because of damaged areas along the complex nerve pathways that are responsible for coordination of movements.Seizures
Seizures — which are the result of abnormal electrical discharges in an injured or scarred area of the brain — have been estimated to occur in 2-5% people with MS, compared to the estimated 3% of the general population.Breathing Problems
Respiration problems occur in people whose chest muscles have been severely weakened by damage to the nerves that control those muscles.Itching
Pruritis (itching) is one of the family of abnormal sensations — such as "pins and needles" and burning, stabbing or tearing pains — which may be experienced by people with MS.Headache
Although headache is not a common symptom of MS, some reports suggest that people with MS have an increased incidence of certain types of headache.Hearing Loss
About 6% of people who have MS complain of impaired hearing. In very rare cases, hearing loss has been reported as the first symptom of the disease.
Secondary and tertiary symptoms
While the primary symptoms described on this page (more and less common) are the direct result of damage to the myelin and nerve fibers in the central nervous system (CNS), the secondary symptoms are the complications that can arise as a result of these primary symptoms. For example:
Tertiary symptoms are the “trickle down” effects of the disease on your life. These symptoms include social, vocational and psychological complications. For example, if you are no longer able to drive or walk, you may not be able to hold down your usual job. The stress and strain of dealing with MS often alters social networks and sometimes fractures relationships. Problems with bladder control, tremor or swallowing may cause people to withdraw from social interactions and become isolated.
Depression is very common in people with MS. Depression may be both a primary and a tertiary symptom as it can be caused by the disease process itself and/or triggered by the challenges discussed above.
- Bladder dysfunction can cause repeated urinary tract infections.
- Inactivity can result in loss of muscle tone and disuse weakness (not related to demyelination), poor postural alignment and trunk control, decreased bone density (and resulting increased risk of fracture), and shallow, inefficient breathing
- Immobility can lead to pressure sores.
