What is Multiple sclerosis (MS)?
Multiple sclerosis (MS) is a condition affecting the brain and spinal cord, in which the immune system mistakenly attacks the protective covering (myelin) around nerve fibres. This disrupts the flow of information between the brain and the rest of the body.
Symptoms vary widely between individuals and can include fatigue, vision problems, numbness or tingling, muscle weakness or spasms, balance difficulties, and problems with thinking or memory. Many people experience a relapsing-remitting pattern, with symptoms flaring up and then easing over time.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Pace your activities.Balancing activity with rest helps manage fatigue, one of the most common and disruptive MS symptoms.
- 2Stay physically active where possible.Regular, gentle exercise tailored to your ability can help with strength, balance, and mood.
- 3Keep cool.Heat can temporarily worsen symptoms for many people with MS, so avoiding overheating can help.
- 4Engage with your MS team.Neurologists, MS nurses, physiotherapists, and occupational therapists can all help manage symptoms and adjust treatment as the condition changes.
- 5Look after your mental health.Living with a long-term, unpredictable condition can affect mood — support groups and counselling can make a real difference.
