MS Symptoms and Signs

Multiple sclerosis can cause a wide variety of different symptoms. They may even mimic other diseases, because:

• Different parts of the brain control different neurological functions
• The spinal cord transmits impulses to and from the brain in a variety of ways
• As MS lesions can affect different parts of the brain and spinal cord, symptoms vary markedly from person to person

There is no real difference between Multiple Sclerosis (MS) symptoms in women and men. Also, two people with MS rarely have the same symptoms. Many people experience a variety of multiple sclerosis symptoms before a firm diagnosis is made. If you believe your symptoms may indicate MS, consult a doctor.

Common Symptoms of MS

The most common symptoms MS are:

• Fatigue:
  A very common symptom of MS, fatigue occurs because the nervous system has to work harder to send signals through damaged nerve pathways, which uses more energy and causes tiredness even after minimal activity.

• Diminished vision:
  Vision problems often happen when the optic nerve becomes inflamed (optic neuritis), disrupting signals between the eye and the brain and causing blurred or dim vision, pain, or colour changes.

• Pain:
  Pain in MS can arise from nerve damage itself (neuropathic pain) or from muscle stiffness and spasms caused by disrupted communication between the brain and muscles.

• Feelings of hot or cold:
  MS can affect the nerves that regulate temperature perception, leading to unusual sensations of heat or cold even when the environment hasn’t changed.

• Pins and needles:
  This tingling sensation is caused by demyelination — damage to the protective coating around nerves — which interferes with normal sensory signals travelling to the brain.

• Numbness:
  When nerve signals are blocked or slowed by MS lesions, it can result in areas of reduced or lost sensation, often in the face, hands, or legs.

• Sensations resembling electric shocks:
  Known as Lhermitte’s sign, these sudden, electric-shock feelings are triggered when damaged nerves in the spinal cord are stretched, usually by bending the neck forward.

• Depression:
  Depression is common in MS due to both the emotional impact of living with a long-term condition and changes in brain chemistry caused by inflammation and nerve damage.

• Heightened sensation:
  Some people experience exaggerated or hypersensitive feelings (like pain from light touch) because of overactive or misfiring sensory nerves affected by MS lesions.

• Weakness, tremors, or dragging leg:
  These occur when nerve damage disrupts signals to the muscles, making them harder to control and leading to weakness, shaking, or difficulty lifting the leg.

• Gait problems:
  Walking difficulties often result from a combination of muscle weakness, stiffness (spasticity), and balance issues, all caused by disrupted nerve communication.

• Speech disorders:
  MS can affect the muscles used for speaking or the brain regions that coordinate speech, leading to slurred, slow, or uneven speech patterns.

• Loss of balance or falling:
  Balance is managed by complex nerve signals between the brain, eyes, and body – when these are disrupted, coordination becomes harder, increasing the risk of falls.

• Altered hearing or taste:
  In rare cases, lesions on the nerves that control hearing or taste can distort how the brain processes these senses, causing temporary or ongoing changes.

What to Do if You Think You Have Symptoms of MS

If you’re noticing symptoms such as fatigue, numbness, vision problems, or changes in balance and movement, it’s natural to feel concerned. These symptoms can be caused by many different conditions, but it’s important to speak to your GP or healthcare professional so you can start finding answers.

Your GP will talk through your symptoms, medical history, and overall health, and may refer you to a neurologist (a specialist in the brain and nervous system) for further assessment. The neurologist may recommend tests such as an MRI scan, lumbar puncture, or nerve function tests to check for signs of inflammation or nerve damage that could suggest MS.

Because MS symptoms can come and go or overlap with other conditions, getting a clear diagnosis can take time. Keeping a record of your symptoms (when they appear, how long they last, and how they affect you) as this can be really useful to share with your healthcare team.

Whether or not you are diagnosed, it would be a good idea to explore the details behind the Overcoming MS Program.  The Program can both help people with MS reduce the frequently and severity of relapses and also help people without MS to live a healthier lifestyle which will reduce their chances of developing MS as well as other well known health conditions.
