Multiple Sclerosis has a multitude of symptoms, some more severe than other, some more disabling then others. The main MS symptoms are:

Fatigue – MS sufferers are affected by normal fatigue, and MS specific fatigue, called lassitude – a feeling of constant sleepiness, besides neuromuscular fatigue.

Spasticity - which is the result of the dysfunction of an upper motor neuron that controls impulse and neurochemistry.

Weakness – appears because of the demyelination, and deconditioning; however, the muscles are only neurologically weakened.

Urinary dysfunction – the symptoms can include incontinence, hesitancy, frequency, urgency, et cetera.
Bowel dysfunction – most commonly constipation

Sexual dysfunction - impotence in men and decreased vaginal lubrication for women.

Pain – a very common symptom, which presents itself in various forms: irritative, burning, dysesthesia, et cetera.
Visual Dysfunction – which can mean loss of color,  blurry vision, phosphenes, and other

Paroxysmal spasms – meaning that the paroxysmal  electrical short-circuiting of the spinal cord, which leads to sensory disturbances and spasms.

Pathological laughing or crying – this occurs when MS demyelination affects the peudobulbar palsy.

Depression – again, the demyelination affects and changes the brain’s neurochemistry, and this leads to depression ( not that having MS it’s in itself depressing).
