Sooner or later, anyone tracking headaches for a disability claim runs into the word prostrating. It turns up in the VA's own criteria, in forum threads, and in a great deal of advice from people who are not service officers.
And the moment someone learns the word, a predictable thing happens: they start writing their symptom log to match it.
That is the single most damaging thing you can do to a record you have spent months keeping, and this guide is mostly about why.
What this guide will not do
It will not tell you what the word means as a legal standard, and it will not tell you what any description is worth. Both of those depend on your specific records and your specific circumstances, and the person qualified to talk about them is an accredited service officer, whose help is free.
What it will do is answer a much narrower question, which is the one that actually blocks people: what do I write down tonight?
What the word is pointing at, in plain English
Strip away the officialese and "prostrating" is describing being laid low. Not carrying on uncomfortably. Stopping. Having to lie down, having to be in the dark, being unable to continue with what you were doing.
That is a useful thing to understand, because it tells you the shape of what matters: not how much it hurt, but what it did to you.
And that is exactly the same thing every other guide here has been telling you to record. The word does not change your method. It just names one end of the spectrum you were already writing down.
Why writing to match the word backfires
Say you have kept a log for eight months. Some entries say "bad headache, took something, got through the day." Some say "had to lie down for three hours." Then you learn the word, and from that point every entry describes a day that flattened you.
Three things have now gone wrong.
The change is visible. A record whose character shifts on a particular date, and never shifts back, tells a reader something about the date rather than about your health. Nobody has to be suspicious for that to be the plain reading.
You have destroyed your own best evidence. The value of a long record is the contrast: some days are worse than others, and here is the pattern. A log where every entry is the worst possible day has no pattern in it. It is a flat line, and a flat line at maximum is less informative than an honest curve.
You have made yourself easier to doubt. Once one part of a record looks written toward a conclusion, the rest of it carries less weight, including the parts that were completely honest.
The test: would you have written the entry this way if you had never heard the word? If not, do not write it that way.
Do not upgrade the past
The related temptation is to go back through old entries and rewrite them in stronger language now that you know which language matters.
Do not. Those entries were written on the day, close to the event, in the words you actually reached for at the time. That is what makes them worth something. Rewritten from eight months' distance with a goal in mind, they become a reconstruction, and a reconstruction is worth much less than the thing it replaced.
If you genuinely under-recorded a period — you were writing two words a day out of exhaustion, and those days were far worse than the entries suggest — say that once, in a dated entry written today, in plain terms. "Looking back at March and April, my entries were much shorter than the days deserved. I was writing one line at bedtime and most of those days I had lost the afternoon." That is honest, it is dated correctly, and it does not pretend to be something written at the time.
What to write instead
The same five things as always: the date it happened, what happened, how bad, how long, and what it stopped you doing. The last one is where all the weight sits, and it does not need a special vocabulary.
Facts, in your own words:
Had to leave work at 1pm. Lay down in the spare room with the blinds shut until about 5. Could not eat. My wife took the kids to practice because I was not safe to drive.
That entry contains no jargon and does not attempt to characterise itself. It says what happened. Whether it satisfies any particular criterion is a determination somebody else makes, from a record that is worth reading precisely because it was not written with that determination in mind.
Record the days you pushed through, too
A lot of veterans, and Marines in particular, are bad at this. The instinct is to carry on, and then not to count it because you carried on.
Carrying on is not the same as being fine, and it belongs in the record:
Worked the whole shift with a headache building all day. Got almost nothing done, had to redo the two invoices I did in the afternoon because I had them wrong. Went straight to bed at 6.
That is a real functional consequence written honestly. It is not the same as a day you lost entirely, and it should not be dressed up as one. But it is not nothing, and if your log only contains the days you were flattened, everything in between vanishes.
If someone tells you to describe every headache as prostrating
Someone will. It is common advice in veteran forums and it is occasionally sold as a service.
It is bad advice, and not for a squeamish reason. It is bad because it takes a record whose value is its credibility and spends that credibility for nothing. An honest record with twelve severe days and forty milder ones says something specific and checkable. The same record with fifty-two identical worst-days says only that somebody wrote fifty-two entries.
You do not have to argue with whoever told you. Just keep writing what actually happened, and take the record to a service officer who can tell you what it shows.
The short version
The word is not a target. Record what the day did to you, in your own words, the same way you did before you heard it. Do not rewrite old entries. Record the days you pushed through as well as the days you could not. An honest record with variation in it is stronger than a uniform one, and it is the only kind that stays strong under scrutiny.
