Levelling up minister Dehenna Davison has resigned from her role in government due to living with chronic migraines.

The 30-year-old MP for Bishop Auckland in County Durham said in her resignation letter to prime minister Rishi Sunak that suffering from the condition has had a “great impact on my ability to carry out the role”.

“Some days I’m fine, but on others it is difficult, if not impossible, to keep up with the demands of ministerial life - and the timing of such days is never predictable,” she wrote. “Though I have tried to mitigate, and am grateful to colleagues for their patience at times, I don’t feel it is right to continue in the role.”

Chronic migraines tend to develop gradually if migraines become more frequent over time. Around 2.5 out of 100 people with episodic migraines (headaches that occur on fewer than 15 days per month) go on to develop chronic migraines.

Some patients may also find certain triggers can cause migraines. According to the NHS, these include:

  • Starting a period

  • Stress and tiredness

  • Not eating regularly

  • Too much caffeine

  • Not getting enough exercise

How can chronic migraines be treated?

If you are experiencing headaches more than 15 days per month, with at least eight having migraine symptoms, you should speak to your GP. It is recommended that you keep a headache diary detailing symptoms to help correctly diagnose chronic migraine.

While there is no cure for migraines, there are several treatment options to help patients manage the condition, including drug and non-drug treatments.


Over-the-counter painkillers like paracetamol, ibuprofen, or aspirin can help reduce symptoms of a migraine. These are most effective if taken at the first signs of a migraine attack, NHS Inform says, and you should not wait until the headache worsens before taking painkillers as it will often be too late.

However, taking too many painkillers can lead to medication overuse headaches, which can make it difficult to treat migraines. You should not take them more than 15 days per month.


If over-the-counter painkillers are ineffective at easing symptoms, GPs may recommend a triptan medicine, which is a specific painkiller for migraine. These are available as tablets, injections and nasal sprays.

Some side-effects of triptans can include flushing and light-headedness, feelings of heaviness in the face, throat, limbs or chest, tingling, nausea, dry mouth and drowsiness. GPs may try prescribing a different type of triptan is the first course of treatment is not effective or causes unpleasant side effects.

Preventive treatment

Preventive treatment aims to reduce how often migraine occurs and their severity. These can include prescriptions of beta-blockers, tricyclic antidepressants, anti-epilepsy drugs and the blood pressure tablet candesartan.

Non-drug options

Certain changes to lifestyle or holistic treatments like acupuncture can sometimes help chronic migraine sufferers to ease their symptoms. These usually work best when used alongside other treatment options.
