Look, I get it. You're lying in a dark room with an ice pack on your head wondering why do I get migraines while everyone else seems fine. I've been there too - missing birthdays, canceling work meetings, that awful throbbing behind your left eye. It's not just a headache, is it? That nausea, light sensitivity, the weird aura... it's a whole-body nightmare. Let's cut through the noise and talk honestly about why this is happening to you.
What Exactly is Happening in Your Brain During a Migraine?
Science used to think migraines were just swollen blood vessels. Turns out, it's way more complex. Your nervous system goes into hyperdrive, releasing inflammatory substances that irritate nerves around your brain. Picture this: your trigeminal nerve (the main facial nerve) gets hypersensitive and starts sending pain signals nonstop. Meanwhile, brain chemicals like serotonin and CGRP (calcitonin gene-related peptide) go haywire. This isn't just "I had a stressful day" stuff - it's a neurological firestorm.
I remember my neurologist sketching this on a napkin during my first appointment. "Your brain's basically overcooked spaghetti right now," he said. Not the most technical explanation, but it stuck with me.
Your Migraine Triggers Aren't Just "Stress" - The Real Culprits
Ever notice how some people can drink red wine and eat chocolate without issues? Meanwhile, you glance at a piece of cheese and boom - migraine city. Your triggers are as unique as your fingerprint. After tracking mine for three years (yes, I'm that person with the color-coded symptom journal), here's what actually matters:
| Trigger Type | Specific Examples | Why It Happens | My Personal Rating (1-10) |
|---|---|---|---|
| Hormonal | Estrogen drops before menstruation, ovulation, menopause fluctuations | Affects serotonin levels and blood vessel function | 9/10 (My worst trigger) |
| Dietary | Aged cheeses, MSG, artificial sweeteners, processed meats, alcohol (especially red wine) | Tyramine, nitrates, and histamine disrupt neurotransmitter balance | 7/10 |
| Sensory | Fluorescent lighting, strong perfumes, loud noises, flickering screens | Sensory overload activates trigeminal nerve pathways | 8/10 |
| Sleep-Related | Getting too much or too little sleep, jet lag | Disrupts hypothalamus function (your brain's regulator) | 6/10 |
| Weather Changes | Barometric pressure drops, high humidity, extreme temperatures | Pressure changes affect sinus cavities and blood flow | 5/10 |
| Dehydration | Even mild dehydration (losing just 1-2% body water) | Reduces blood volume and oxygen flow to the brain | 8/10 (Surprisingly brutal) |
Honestly? I used to roll my eyes at the dehydration thing until I did a test week with 3 liters of water daily. My migraine days dropped from 4 to 1 that week. Annoyingly simple fix.
The Genetic Hand You Were Dealt
Ever asked "why do I get migraines" while your sister doesn't? Blame your parents. If one parent has migraines, you've got 50% chance. Both parents? Up to 75% chance. Researchers have identified over 40 genetic regions linked to migraine susceptibility. The big players:
- TRESK gene mutation: Causes nerve cells to become hyperexcitable
- CACNA1A gene: Affects calcium channels in brain cells (common in familial hemiplegic migraine)
- MTHFR gene variant: Impacts how you process B vitamins and homocysteine
My cousin and I both have the MTHFR mutation. We call it our "migraine gene" - dark humor gets us through.
Migraine Types Explained - Which One is Wrecking Your Life?
Not all migraines are created equal. Knowing your type changes everything for treatment:
| Type | Key Features | Duration | Treatment Approach |
|---|---|---|---|
| Migraine Without Aura (Most Common) | Throbbing pain on one side, nausea, light/sound sensitivity | 4-72 hours | Triptans, NSAIDs, anti-nausea meds |
| Migraine With Aura | Visual disturbances (zigzags, blind spots), tingling, speech issues BEFORE pain | Aura: 20-60 min Pain: 4-72 hours |
Careful timing with triptans (avoid during aura) |
| Chronic Migraine | Headache ≥15 days/month with migraine features ≥8 days | Constant cycle | Preventatives (CGRP inhibitors), lifestyle overhaul |
| Vestibular Migraine | Vertigo, dizziness, balance issues - sometimes WITHOUT headache | Minutes to days | Vestibular rehab, motion sickness meds |
| Hemiplegic Migraine (Rare) | Weakness on one side, mimics stroke - REQUIRES emergency eval | Hours to days | Specialist management only |
Red Flags Needing IMMEDIATE Care:
• Thunderclap headache (sudden severe pain)
• Headache after head injury
• Weakness/numbness that's NEW or DIFFERENT
• Pain that wakes you from sleep
• Personality changes or confusion
Don't gamble with these - my ER nurse friend sees missed strokes weekly.
Proven Fixes: Beyond the Basic "Drink Water" Advice
Okay, let's get practical. When you're desperate to know why do I get migraines, you really want solutions. After 15 years of trial/error and consulting top neurologists, here's what actually moves the needle:
Medications That Work (and Some That Don't)
The migraine medication landscape changed dramatically since 2018 with CGRP inhibitors. Here's the real scoop:
| Medication Type | Examples | Best For | Cost/Month* | Effectiveness Rating |
|---|---|---|---|---|
| CGRP Inhibitors (Preventative) | Aimovig, Emgality, Ajovy, Vyepti | Chronic migraine (>4/month) | $600-$1,200 (copay programs help) |
★★★★☆ (Reduced mine 60%) |
| Triptans (Acute) | Sumatriptan, Rizatriptan, Eletriptan | Stopping attacks once they start | $30-$300 | ★★★☆☆ (Works best if taken early) |
| Gepants (Acute/Preventative) | Ubrelvy, Nurtec, Qulipta | Can't tolerate triptans or with CVD risk | $900-$1,000 | ★★★★☆ (Faster relief than triptans for me) |
| Beta-Blockers | Propranolol, Metoprolol | Prevention, especially with anxiety | $4-$25 | ★★☆☆☆ (Caused fatigue for me) |

Non-Drug Weapons for Your Arsenal
Pills aren't everything. These evidence-backed tools deserve space in your migraine toolkit:
- Cefaly Device: FDA-cleared wearable that stimulates trigeminal nerve ($350-$500 one-time cost)
- Nerivio Band: Smartphone-controlled armband using remote electrical neuromodulation ($99/month subscription)
- Ginger Supplementation: 500-600mg powdered ginger at onset - matches sumatriptan effectiveness in studies (source)
- Ice Helmets: Sounds ridiculous but the Thermalon Headache Hat ($40) got me through grad school
- Riboflavin (B2): 400mg/day reduced migraine days by 50% in clinical trials after 3 months
My combo: Ubrelvy + Cefaly + ice hat + caffeine (yes really - 100mg exactly). Skipping any piece risks failure. Find your formula.
Your Burning Questions Answered (No Fluff)
Let's tackle the real stuff people search when wondering why do I get migraines:
Why do I get migraines when it rains?
Barometric pressure drops make tissues swell, irritating nerves. Solutions: Stay hydrated, use decongestants preventatively, try WeatherX earplugs ($15) that equalize pressure.
Why do I get migraines after I eat?
Likely histamine or tyramine sensitivity. Common triggers: aged cheeses, processed meats, citrus, leftovers >24 hours old. Try a low-histamine diet for 4 weeks.
Why do migraines make me throw up?
Migraines activate the vomiting center in your brainstem. Anti-nausea meds like ondansetron dissolve on your tongue when you can't keep pills down.
Why do I get migraines on weekends?
"Let-down stress" - cortisol drops suddenly triggering attacks. Avoid sleeping in (set alarm within 1 hour of weekday wake time), stay hydrated, limit alcohol.
Can neck problems cause migraines?
Absolutely. Cervicogenic headaches mimic migraines. See a physical therapist specializing in the Watson Headache Approach. Correcting my forward head posture reduced attacks 30%.
Putting It All Together
Figuring out why do I get migraines isn't about one magic bullet. It's about your unique biology meeting your environment. Track diligently for 3 months - apps like Migraine Buddy help spot patterns. Push for specialist care if over-the-counter meds fail. New treatments emerge constantly - what didn't work 5 years ago might be your solution now. Most importantly? You're not broken. Your nervous system is just wired intensely. With the right tools, you can rebalance it. Start tomorrow: Drink that glass of water, set consistent sleep hours, and maybe hide your coworker's overpowering perfume.
