Migraine C&P Exam: 5-Minute Prep

Before your exam

Keep a headache log for 2–3 months: date, hours, severity 1–10, symptoms, and what you had to stop doing. Bring it.
Bring work records: sick days, FMLA, a supervisor note about missed or reduced work.
Bring prescription history: triptans, preventives, Botox, nerve blocks, and any ER visits.
Count your prostrating attacks per month and know that number cold.
Get a buddy statement from someone who has seen you lying in a dark room, vomiting, unable to function.

During the exam

What the examiner measures

The examiner is scoring two things: how often you have prostrating attacks (you must stop everything and lie down) and whether they cause severe economic inadaptability (they keep you from working).

Pain level by itself is not the rating.

Three things to say or show

Use the word. “My migraines are prostrating. When one hits I have to stop and lie in a dark room for X hours.”
Give the real frequency. “About 4 prostrating attacks a month, each 8–24 hours.” Don’t round down.
Tie it to work. Days missed, left early, duties you can’t do, a job you lost or turned down. That is what “economic inadaptability” means.

Mistakes that sink ratings

“I get headaches a few times a month.” Vague frequency and no “prostrating” language reads as 0% or 10%.
Showing up on a good day without saying so. Tell the examiner: “Today is a good day. On a bad day this is what happens.”

After

Request the exam report (DBQ). Check that it says “prostrating,” records your monthly frequency, and notes the work impact.
If it doesn’t, send your log and a short statement (VA Form 21-4138) to the file.
Keep the log going. It is your best evidence at every future exam.

Go deeper: regulations, secondaries and why this works

What "prostrating" means

Prostrating means the attack forces you to stop and rest: lying in a dark room, unable to work or do daily tasks, nausea or vomiting, light and sound sensitivity that makes you isolate.

A headache you push through at your desk is not prostrating. One that sends you home is.

Symptoms that complete the picture

Aura, nausea, vomiting, light and sound sensitivity, vertigo, and side effects of preventive medication (drowsiness, brain fog, weight gain) all describe the real impact. Mention them; don’t make the examiner guess.

Secondary connections

Migraines are often secondary to traumatic brain injury, PTSD or anxiety (stress is a documented trigger), cervical spine conditions, sleep apnea, or medications for other service-connected conditions.

Migraines can in turn cause depression or anxiety. Each link can be a separate claim.

The regulation

Migraines are rated under 38 CFR 4.124a, diagnostic code 8100. The 50% level requires both frequency and economic impact, which is why work documentation is listed in the must-dos.
