Don’t Ignore These 5 Early Warning Signs of Multiple Sclerosis

Don’t Ignore These 5 Early Warning Signs of Multiple Sclerosis
Multiple sclerosis (MS) is a disease that affects your central nervous system. One million Americans have MS, and the earliest symptoms aren’t always easy to point out as “MS symptoms.” In fact, they’re rather vague. Read on to learn more.

Multiple sclerosis (MS) is a neurological disease that affects your brain and spinal cord. While it can cause chronic pain and coordination issues, it doesn’t always start with obvious symptoms. 

In fact, many of the earliest warning signs can feel vague, like unexplained fatigue, tingling, or changes in vision that come and go. Because these symptoms can seem minor, people sometimes dismiss them or wait months before seeking medical advice. 

That’s why our primary care team at Link Integrated Healthcare, in Camarillo, Northridge, Oxnard, Simi Valley, and Santa Barbara, California, wants to take a moment to highlight five of the earliest warning signs of multiple sclerosis. 

1. Vision problems

Vision problems are the first sign of MS in about 25% of people with MS. About 80% of people with MS experience optic neuritis, which occurs when inflammation affects their optic nerve.

MS-related eye symptoms may include:

  • Blurred or dim vision
  • Pain when moving the eye
  • Loss of color vision
  • Temporary vision loss in one eye

These symptoms may develop suddenly and often affect only one eye. 

2. Numbness or tingling

Unexplained numbness or tingling in the face, arms, legs, or fingers can be an early sign of multiple sclerosis. Many people describe the sensation as pins and needles, burning, or a patch of skin that suddenly feels “asleep” or less sensitive than usual.

Because MS disrupts how nerves send signals, these sensations may appear in different areas of the body and may come and go. One day it might affect your hand or arm, and another time it may show up in your leg or face.

To make things more confusing, MS isn’t the only condition that can cause these symptoms. Other issues, such as peripheral neuropathy, can also lead to numbness or tingling in the arms, legs, or feet.

That’s why it’s important not to ignore persistent or unexplained nerve sensations. A neurological evaluation is the best way to determine what’s causing your symptoms and whether further testing is needed.

3. Persistent fatigue

Many people with MS (an estimated 80%!) experience fatigue that is more intense than typical tiredness. 

MS-related fatigue may:

  • Occur even after a full night’s sleep
  • Worsen as the day goes on
  • Make everyday tasks feel unusually difficult
  • Worsen with heat or physical activity

Because fatigue is such a common symptom in everyday life, it’s sometimes dismissed, but persistent or unusual fatigue can be an important clue.

4. Problems with balance or coordination

MS can affect the parts of your nervous system responsible for movement and coordination. This means you may experience unsteadiness while walking, dizziness, difficulty with coordination, and feeling off balance.

These issues may appear intermittently or gradually worsen over time.

5. Bladder issues

MS can disrupt the signals between your brain and bladder.  In fact, the National Multiple Sclerosis Society reports that about 80% of people with MS experience bladder problems at some point during the condition.

Some people may notice symptoms such as:

  • Frequent urges to urinate
  • Difficulty fully emptying the bladder
  • Sudden urgency
  • Occasional bladder leakage

These symptoms can be frustrating and sometimes embarrassing, but they are actually very common in people with MS.
