Menstrual Migraine: When Your Cycle Becomes the Trigger
If your migraines follow a predictable pattern tied to your cycle, arriving in the days before your period, during it, or around ovulation, you’re likely dealing with menstrual or hormonal migraine. It’s one of the most common and frequently undertreated forms of migraine, and one of the hardest to manage without understanding the mechanism driving it.
Menstrual migraine affects a significant proportion of women who experience migraines and tends to be more severe, longer-lasting, and less responsive to standard treatment than migraines that occur at other times of the month. We see women and girls of all ages, including teenagers whose migraines have appeared around the start of their cycles.
Menstrual migraines come in two forms: Pure menstrual migraine occurs only around menstruation, typically starting on day one of the cycle and in at least two out of three consecutive cycles. Menstrual-related migraine also peaks around the period but occurs at other times of the month too, often around ovulation. Knowing which type you have shapes how we approach treatment.
Other Symptoms of menstrual migraines
Other symptoms that may be experienced include:
- Pulsating or throbbing pain on one or both sides of the head
- Sensitivity to light, sound, and smell
- Nausea and/or vomiting
- Visual disturbances (known as an ‘aura’) or loss of vision
- Muscle tightness and soreness (specifically in the head, face, neck, and shoulders)
- Aching joints
- Loss of appetite
- Fatigue
- Irritability
- Dizziness and confusion
Causes of Menstrual Migraines
Menstrual migraines were long assumed to be purely hormonal, driven by fluctuations in oestrogen and progesterone across the cycle. That explains the timing. It doesn’t explain why some women are severely affected and others aren’t.
Recent research suggests that a sensitised trigeminal cervical nucleus (TCN) is a primary contributing factor for hormonal migraines. Hormonal changes trigger the blood vessels in our heads to expand and contract. For some women, their TCN may incorrectly read these normal oestrogen and progesterone fluctuations as harmful, which leads to a severe headache.
How are Menstrual Migraines treated?
Menstrual migraines are typically harder to treat than non-hormonal migraines. That’s a clinical reality we’re upfront about. It’s also why the approach needs to be more targeted. The options we work with include:
- Watson Headache® Approach: This is a series of manual, non-manipulative cervical techniques that seek to decrease overstimulation of the TCN so that hormone fluctuations are no longer a trigger.
- Exercise: Stress is a recognised trigger for menstrual migraines. Targeted rehabilitation exercise, including cervical strengthening and movement-based stress management, can reduce migraine frequency for some patients. Your clinician will advise whether this is relevant for your presentation.
- Dry Needling: Similar to acupuncture, this technique involves inserting thin needles into specific myofascial trigger points to stimulate the muscles and release tension.
- Supplements: Some research suggests magnesium supplementation in the second half of the menstrual cycle may reduce migraine frequency for some women. We’d recommend discussing this with your GP or pharmacist to confirm it’s appropriate for you before starting.
- Medications: Pharmacological management, including hormonal therapies, triptans, and NSAIDs, is outside our scope as osteopaths and is best managed by your GP or a neurologist. If medication is part of your management, our treatment works alongside it rather than instead of it. We’re happy to communicate with your prescribing doctor where that’s useful and where you consent.
FAQ regarding menstrual/hormonal migraines
There is no single diagnostic test. Menstrual migraine is identified through pattern recognition, which is why tracking your cycle alongside a headache diary is one of the most useful things you can do before your first appointment. Recording when headaches start, how long they last, their severity, and where you are in your cycle gives your clinician the information needed to identify whether there’s a hormonal pattern and rule out other causes.
At your first appointment, we’ll take a detailed clinical history and carry out a physical assessment of the upper cervical spine. This helps us determine whether there’s a cervical component contributing to your migraines alongside the hormonal trigger, which is often the case and is frequently missed in standard headache assessments.
For some women, yes. Migraines often improve during pregnancy as oestrogen levels rise and stabilise, and some women find they reduce or stop altogether after menopause. But this isn’t universal, and the path there isn’t always straightforward.
Perimenopause in particular can make things worse before they get better. Fluctuating oestrogen levels during the years leading up to menopause often increase both the frequency and severity of hormonal migraines. If your migraines have worsened in your 40s, perimenopause is worth discussing with both your GP and your clinician here.
Several conditions follow the menstrual cycle and can feel similar to hormonal migraine. The most common ones worth knowing about:
Dysmenorrhea refers to painful periods accompanied by cramping and sometimes systemic symptoms including headache and nausea. Unlike menstrual migraine, the headache is typically secondary to the period pain rather than a primary neurological event.
Low oestrogen beyond normal cycle fluctuations, for example from conditions like hypothalamic amenorrhoea, early menopause, or certain medications, can trigger head pain that doesn’t follow the usual menstrual pattern.
Premenstrual dysphoric disorder (PMDD) is a more severe form of PMS that includes significant mood, cognitive, and physical symptoms in the luteal phase of the cycle. Headache can be one feature, but the broader symptom picture is what distinguishes it.
If you’re unsure which of these applies, that’s exactly what a thorough clinical history is designed to help sort out. Your GP is also an important part of this conversation.
Yes, for many women it is. Hormonal changes are the trigger, but the trigeminal cervical nucleus, the structure in the brainstem that processes pain signals from the head and upper neck, needs to be sensitised for those hormonal changes to produce a migraine. The Watson Headache Approach works by reducing that sensitisation through targeted manual treatment of the upper cervical spine. For some women this reduces the frequency and severity of menstrual migraines significantly, even though the hormonal trigger itself hasn’t changed.
Whether it’s relevant for your specific presentation is something we assess at your first appointment.
Perimenopausal migraines are one of the most frustrating presentations because they often don’t respond as well to the approaches that worked earlier in life. Hormonal fluctuations during this period are more erratic and harder to predict.
What we can assess is whether there’s a cervical component that’s been amplifying your sensitivity throughout your migraine history and that may be making the perimenopausal transition harder. This is worth investigating before assuming the worsening is entirely hormonal. We see women at all stages of this transition and we’re upfront about what treatment can and can’t achieve.
