The speed of Multiple Sclerosis (MS) progression is highly variable, ranging from very rapid disability accumulation in some individuals (even severe within years) to extremely slow progression where people remain largely functional for decades, with most cases starting as relapsing-remitting MS (RRMS) that may transition to secondary progressive MS (SPMS) over 5-15+ years, marked by steady worsening rather than flares. Progression is often measured by the Expanded Disability Status Scale (EDSS), with different MS types (RRMS, SPMS, Primary Progressive MS (PPMS)) showing distinct patterns, from episodic attacks to gradual decline.
In many patients, over a span of 5 to 15 years, the attacks begin more indolently, persist more chronically and remit less completely, gradually transforming into a pattern of steady deterioration rather than episodic flares.
Some of the most common symptoms include:
The study found that later-presenting patients often had five to 10 years of prodromal symptoms like fatigue and generalized weakness before getting a diagnosis of MS. “They had been going to doctors for years, but the diagnoses were continually missed,” Zachariah says.
Most people with MS will experience their first distinct symptoms in their 20s or 30s, according to Dr. Alchaki. Some may experience minor, unexplained symptoms sporadically for years before receiving a diagnosis in their 40s and 50s.
The exact cause of Multiple Sclerosis (MS) is unknown, but it's triggered by a combination of genetic susceptibility, environmental factors (like low Vitamin D, infections, smoking, and stress), and immune system dysfunction that leads the body to attack its own nervous system. Triggers that can worsen existing MS include heat, infections, stress, lack of sleep, and childbirth, while factors like smoking, obesity, and low sun exposure increase risk or severity.
Lifestyle and home remedies
Neurological examination
There are some simple tests that a neurologist may carry out if they suspect MS. These involve checking your movement, coordination, vision, balance and reflexes. They can indicate if and where any damage to central nervous system has taken place.
The 'MS hug' is symptom of MS that feels like an uncomfortable, sometimes painful feeling of tightness or pressure, usually around your stomach or chest. The pain or tightness can feel like a tight band stretching under your breasts, around the ribs and back or stomach, or it can be just on one side.
The term benign MS is sometimes used to describe a version of relapsing remitting MS with very mild or no attacks separated by long periods with no symptoms. 'Benign' means 'something doesn't cause any harm'.
Magnetic resonance imaging (MRI) and MS
Magnetic resonance imaging scans (MRI) are vital in diagnosing MS and in monitoring and predicting how someone's MS is changing.
Invisible symptoms of MS – fatigue, pain, blurred vision, numbness, and brain fog – which often go unnoticed by other people, can also interfere with daily functioning and be just as debilitating.
The diagnostic hallmark of MS is the presence of large confluent demyelinated lesions in the white and gray matter of the CNS (Fig. 1) (Charcot 1880). The most important feature is the selective and primary nature of demyelination with the destruction and loss of oligodendrocytes (Babinski 1885; Prineas 1985).
Research suggests that stress can worsen MS symptoms, triggering flare-ups and increasing fatigue (National Multiple Sclerosis Society). Managing mental health proactively can help stabilize symptoms, improve well-being, and enhance overall quality of life.
A small number of people with MS will have mild symptoms with little disability, but others will experience worsening symptoms that will lead to increased disability over time. Most people with MS have short periods of symptoms that resolve fully or partially after they appear.
Heavy Legs & Multiple Sclerosis
They may also ache and hurt. Some people with MS describe it as like having bags of sand attached to their legs. This muscle weakness combined with MS fatigue can be upsetting. Weakness in your legs can cause balance and walking difficulties and you may be more likely to fall.
The most common pains in people with MS are burning pain in the legs or arms, back pain, painful spasms, trigeminal neuralgia (stabbing, intermittent facial pain), and Lhermitte's sign (shock-like sensation down the back and into the arms when dipping your chin to your chest).
Up to ~40% of all MS patients experience constipation at some point in their illness. Some people can be severely constipated and experience bloating and abdominal pain.
Three key warning signs of Multiple Sclerosis (MS) often involve vision problems (like blurred vision or pain with eye movement), numbness or tingling sensations, and fatigue, along with balance issues, weakness, and coordination difficulties, though symptoms vary widely and can include cognitive or bladder problems too.
Based on what we know so far, MS is not an inherited disease. This means that it's not passed down from parents to children. However, the genetic factors that contribute to MS are complex. If you have MS, your children may be more likely to develop MS later in life compared to a child whose parents do not have MS.
More specifically, a brain or head MRI can show if there are any abnormalities in your brain or the surrounding tissues, including, but not limited to: Inflammation and swelling. Structural issues. Abnormal growths or masses.
So in certain cases, your provider may do a mental health screening before or after a neurological exam. A neurological examination typically assesses movement, sensation, hearing and speech, vision, coordination, and balance. It may also test mental status, mood, and behavior.
Eating foods high in saturated fats can harm your health. Red meat and full-fat dairy products should be eaten less. They can cause inflammation, making MS symptoms worse. says, “Dietary changes can significantly impact the management of MS.”
Over 90% of people with MS have elevated levels of an antibody called intrathecal immunoglobulin G (IgG).
Though dizziness can have many causes, MS-related dizziness is typically more severe and lasts for at least two days. You may feel off-balance and unsteady, like you can barely walk without holding onto something.
