Multiple sclerosis (MS) is a lifelong condition affecting the brain and nerves, and there are a number of warning signs to look out for.
Inflammation can occur in parts of the brain or spinal cord which causes symptoms and it is estimated around 130,000 people in the UK live with the condition.
Affected nerve fibres can become vulnerable to damage, and over time may be lost entirely. When this happens, messages can no longer get through and symptoms become permanent.
