Fibromyalgia is a chronic condition of widespread pain and fatigue. The condition has been documented in medical literature since the 1800s, when physicians wrote about a condition that leads to pain, fatigue and disturbed sleep. It is estimated 1 in 20 people in the UK live with fibromyalgia.

As well as widespread pain, patients with fibromyalgia may also have:

• Increased sensitivity to pain

• Fatigue

• Muscle stiffness

• Difficulty sleeping

• Problems with mental processes (sometimes called 'brain fog')

• Headaches

• Stomach pain

There is no specific test for fibromyalgia, which can make it difficult to diagnose. However, symptoms can be managed with the appropriate care.

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.
