Multiple sclerosis (MS) can cause a wide range of symptoms
and affect any part of the body. Each person with the condition is affected
differently.
The symptoms are unpredictable. Some people's symptoms
develop and worsen steadily over time, while for others they come and go.
Periods when symptoms get worse are known as relapses.
Periods when symptoms improve or disappear are known as remissions.online medicine
Some of the most common symptoms include:
- fatigue
- vision problems
- numbness and tingling
- muscle spasms, stiffness and weakness
- mobility problems
- pain
- problems with thinking, learning and planning
- depression and anxiety
- sexual problems
- bladder problems
- bowel problems
- speech and swallowing
difficulties
Most people with MS only have a few of these symptoms.
See a GP if you're worried you might have early signs of
MS. The symptoms can be similar to several other conditions, so they're
not necessarily caused by MS.
Fatigue
Feeling fatigued is one of the most common and troublesome
symptoms of MS.
It's often described as an overwhelming sense of exhaustion
that means it can be a struggle to carry out even the simplest activities.
Fatigue can significantly interfere with your daily
activities and tends to get worse towards the end of each day, in hot weather,
after exercising, or during illness.
Vision problems
In around 1 in 4 cases of MS, the first noticeable symptom
is a problem with one of your eyes (optic neuritis).
You may experience:
- some temporary loss
of vision in the affected eye, usually lasting for days to
weeks
- colour blindness
- eye pain, which is usually worse when moving the eye
- flashes of light when moving
the eye
Other problems that can occur in the eyes include:
- double vision
- involuntary eye movements,
which can make it seem as though stationary objects are jumping around
Occasionally, both of your eyes may be affected.
Abnormal sensations
Abnormal sensations can be a common initial symptom of MS.
This often takes the form of numbness or tingling in
different parts of your body, such as the arms, legs or trunk, which typically
spreads out over a few days.
Muscle spasms, stiffness and
weakness
MS can cause your muscles to:
- contract tightly and painfully (spasm)
- become stiff and resistant to movement (spasticity)
- feel weak
Mobility problems
MS can make walking and moving around difficult,
particularly if you also have muscle weakness and spasticity.
You may experience:
- clumsiness
- difficulty with balance and co-ordination (ataxia)
- shaking of the limbs (tremor)
- dizziness and vertigo, which can make it feel
as though everything around you is spinning
Pain
Some people with MS experience pain, which can take 2 forms.
Pain caused by MS itself (neuropathic
pain)
This is pain caused by damage to the nervous system.
It may include:
- stabbing pains in the face
- a variety of sensations in the
trunk and limbs, including feelings of burning, pins and needles, hugging
or squeezing
Muscle spasms can sometimes be painful.
Musculoskeletal pain
Back, neck and joint pain can be indirectly caused by MS,
particularly for people who have problems walking or moving around that puts
pressure on their lower back or hips.
Problems with thinking,
learning and planning
Some people with MS have problems with thinking, learning
and planning, known as cognitive dysfunction.
This can include:
- problems learning and remembering new things –
long-term memory is usually unaffected
- slowness in processing lots of information or
multitasking
- a shortened attention span
- getting stuck on words
- problems with understanding and processing visual
information, such as reading a map
- difficulty with planning and problem solving – people
often report that they know what they want to do, but can't grasp how to
do it
- problems with reasoning, such
as mathematical laws or solving puzzles
But many of these problems aren't specific to MS and can be
caused by a wide range of other conditions, including depression and anxiety,
or even some medicines.
Mental health issues
Many people with MS experience periods of depression. It's unclear whether this is
directly caused by MS or the result of the stress of having to live with a
long-term condition, or both.
Anxiety can
also be a problem for people with MS, possibly because of the unpredictable
nature of the condition.
In rare cases, people with MS can experience rapid and
severe mood swings, suddenly bursting into tears, laughing, or shouting angrily
for no apparent reason.
Sexual problems
MS can have an effect on sexual function.
Men with MS often find it hard to obtain or maintain an
erection (erectile dysfunction).
They may also find it takes a lot longer to ejaculate when
having sex or masturbating, and may even lose the ability to ejaculate
altogether.
For women, problems include difficulty reaching orgasm, as
well as decreased vaginal lubrication and sensation.
Both men and women with MS may find they're less interested
in sex than they were before.
This could be directly related to MS, or it could be the
result of living with the condition.
Bladder problems
Bladder problems are common in MS.
They may include:
- having to pee more frequently
- having a sudden, urgent need to pee, which can lead to
unintentionally passing urine (urge
incontinence)
- difficulty emptying the bladder completely
- having to get up frequently during the night to pee
- recurrent urinary tract infections (UTIs)
These problems can also have a range of causes other than
MS.
Bowel problems
Many people with MS also have problems with their bowel
function.
Constipation is
the most common problem. You may find passing stools difficult and pass
them much less frequently than normal.
Bowel incontinence is less common, but is often linked to constipation.
If a stool becomes stuck, it can irritate the wall of the
bowel, causing it to produce more fluid and mucus that can leak out
of your bottom.
Again, some of these problems aren't specific to MS and can
even be the result of medicines, such as medicines prescribed for pain.
Speech and swallowing
difficulties
Some people with MS experience difficulty chewing
or swallowing (dysphagia) at
some point.
Speech may also become slurred, or difficult to
understand (dysarthria).
