Multiple sclerosis is a disease which affects the nerve cells of your brain and spinal cord. It is an autoimmune disease, meaning that your immune system starts to damage your body's own cells. Doctors do not fully understand what causes multiple sclerosis.

There are different variants of multiple sclerosis and patients may experience different rates of progression. For many, multiple sclerosis symptoms arise for a short period of time and then disappear. Symptoms may be present for a matter of days or weeks, then subside for up to years. Pain can be felt as burning, tingling or stabbing in different parts of your body. This happens as damaged nerves send a signal to your brain, which your brain interprets as pain.

There is no cure for multiple sclerosis. Treatment aims to reduce how frequently you develop symptoms, decreasing the amount of the pain that you feel. Treatment includes a mixture of medications and physical activity to help strengthen and support your body.

Yes, Medical Cannabis is legal in the UK. Since the law was passed in 2018, Medical Cannabis is allowed for the treatment of chronic pain conditions if other treatments have proven ineffective. Our consultants are pain specialists with experience working with Medical Cannabis.

There is ongoing global research and real-world data that shows the efficacy of Medical Cannabis. It may benefit chronic pain sufferers where other first-line medications have failed.

Medical cannabis works by acting on your endocannabinoid system (ECS). This exists in each of us and helps functions including pain control, sleep and mood.

For example, our own data has shown:

• 94% of patients reported an improvement in the severity of their pain

• 77% of patients reported improvement in mental health

• 88% of patients improved in at least component of quality of life

• 59% of patients using opioids reported they stopped all use

• 97.09% experienced no adverse effects

Your consultant will make sure that you start on a concentration and dose/titration of Medical Cannabis that does not make you feel high.

They'll start you on a low dosing schedule, like you might have seen on other medications. For example "0.1ml twice daily, increase by 0.1ml every 3 days up to 0.5ml maximum".

From there you are in full control of how quickly you increase up to the maximum daily dose.

It's important you follow this schedule intuitively. If you were to feel any side-effects you can contact us immediately.

Any side effects of medical cannabis are more likely to occur when your treatment first starts.
