Criteria

Inclusion Criteria:

• Participants must meet the diagnostic criteria for chronic migraine (headache that have occurred on at least 15 days per month, for at least three months. At least eight of the headache episodes must be typical for migraine).

• Participants must be able to understand and give informed consent to participate in the study.

• Participants must not have medical conditions that require use of drugs that can affect the headache pattern (for example rheumatic disorders).

• Participants must not suffer from malignant diseases.

• Participants must not plan to make changes to existing prophylactic headache medication during the study. Patients may, if already on treatment, choose to continue this throughout the course of the study, or choose to stop the prophylactic treatment at least one week before the start of the baseline period.

• Participants must not be pregnant or plan pregnancy during the course of the study.

• Participants must not breastfeed or plan to do so during the study.

• Participants must not have any contraindications to injection therapy (such as disease with increased bleeding tendency or treatment with certain types of blood thinners).
