When you have multiple sclerosis (MS), your immune system attacks your central nervous system, affecting your brain, spinal cord, and optic nerves. Symptoms can vary, and come and go, making it sometimes hard to diagnose. You could have one symptom, and then months or years later have a completely different one, not realizing the two are related. In one study, people went an average of 7 years between their first MS symptom and their diagnosis.
So, learn the common early symptoms of MS. It may help you get diagnosed and treated quicker.
For many people, the first symptom of multiple sclerosis is in their eyes. Often, MS causes optic neuritis, a condition that damages the nerve connecting the eye to the brain. It usually affects just one eye, but in rare cases it involves both. Symptoms include:
Colors that appear dull
Pain in the eye, especially when you move it
Often, the symptoms get better on their own within a few weeks or months. But if you have these symptoms, go to your doctor right away.
Other eye conditions linked to MS bring on double vision and involuntary eye movements.
The first symptoms of MS may also be unusual sensations around your body, including:
An electric-shock-like feeling when you move your head or neck; it may travel down your spine or into your arms or legs.
Numbness, often in the face
A feeling of tightness or swelling
Another common early symptom of MS is extreme tiredness. You may feel exhausted even if you haven’t been very active. You may be tired as soon as you wake up in the morning.
When you exercise, you may get tired and weak as soon as your body warms. You may also have trouble controlling certain body parts, like your foot or leg, while your body is warmed up. As you rest and cool down, these symptoms are likely to go away.
MS can lead to worse coordination, making it hard to walk. Symptoms can include:
Trouble keeping your balance
Trouble walking with your usual gait
Depending on which part of your nervous system is affected, other early symptoms can include:
Trouble thinking clearly
Bladder and bowel problems
A sense that the room is spinning, a condition called vertigo
Talk to Your Doctor About Your Symptoms
If you’ve had one or more symptoms that are common with MS, your doctor may suggest tests. These can include:
Blood tests to look for other problems with MS-like symptoms, like Lyme disease
A test to measure the speed of signals traveling along your nerves
An MRI, which creates images of your brain, so your doctor can check for areas of damage
A spinal tap to check the fluid that flows in your brain and spinal cord; this may show signs that your immune system is harming your nervous system, which is what happens in MS.
