MS is a complex condition that everyone experiences differently. For many people, MS symptoms can fluctuate from day to day, so it may be hard to know if changes are part of a relapse or not. The most common type of MS is relapsing remitting MS (RMMS), which is characterised by its relapses.
If you think you are experiencing an MS relapse (also known as an attack or flare up), please speak to your neurologist, an MS nurse or GP (general practitioner), as soon as possible. Even if you don’t think you need medical treatment, it’s important to report each relapse to your medical team. This helps them to ensure you are getting the right MS treatment for you, monitor patterns in your symptoms, track how MS is affecting you, and more accurately provide you with care and support.
Common MS relapse symptoms
- Worsening fatigue
- Weakness, particularly arms or legs
- Numbness and altered sensations
- Changes in thinking and concentration
- Loss of balance and coordination
- Changes in bladder function
- Eyesight problems, such as blurred or double vision.

How to recognise a relapse
- New symptoms appear or old symptoms get worse
- Symptoms last for at least 24 hours
- At least 30 days has gone by since your last relapse symptoms
- There must be no other reason for the symptoms, such as stress, heat or an infection
A relapse can include new rapid-onset symptoms or a slower but noticeable change over a few days. New symptoms may appear or existing symptoms get worse.
Relapse recovery varies depending on several factors. In most cases, it takes time for the inflammation to settle and to return to your previous baseline, or establish a new baseline.
When experiencing a relapse or flare up, it’s natural to feel a range of emotions, such as uncertainty, fear and confusion. You can take steps to manage relapses and plan for them, so they have less of an impact on your life and your wellbeing.
Signs it may not be a relapse
Symptoms may get worse for other reasons; this is called a pseudo relapse. The reasons can include:
- Infections
- Stress or tiredness
- Heat or cold
- Menstruation
- Long periods of inactivity or lack of exercise
How to manage a relapse
Relapse symptoms vary from person to person. Generally, symptoms gradually worsen over a few days before they reach a peak and then recover. Not all relapses need to be treated and may go away on their own. They could last for a few days or for several weeks.
Your health practitioner may treat the relapse itself or use management strategies for the symptoms. This could include a short course of steroids or other treatments. It may also include allied health services, such as:
- Physiotherapy
- Occupational therapy
- Neuropsychology
- Speech and language therapy
- Rehabilitation

Reduce your risk of relapses
Long-term disease modification therapies for MS will reduce the risk of relapses.
To reduce your chance of having a pseudo relapse, it’s worth reducing any potential triggers and looking after your general health. For example, regular exercise and eating a well-balanced diet can help you stay healthy and reduce the risk of triggers such as infections. Smoking may also increase your risk of relapses and your condition progressing.
