Tracking with fibro fog

NIAMS lists problems with concentrating, thinking clearly and memory among the symptoms of fibromyalgia, and says they are sometimes called “fibro fog”. That sentence is the only claim about a body on this page.

Everything below it is about a form: how many fields it has, what they are called, and how an entry gets made. These are design choices. They are not treatment, and a shorter form does not change concentration, memory or symptoms. A shorter form has fewer fields. That is the whole of what it changes.

A long form is not a wrong form, and a short one is not a lesser version of it. They are two forms. The choice described here is whether to keep a second, shorter one alongside the long one, and which fields it holds.

One list a form’s fields could be drawn from is what a doctor asks about. NIAMS says a doctor taking a medical history will likely ask about the location, severity and duration of pain, and about severe fatigue or cognitive problems (NIAMS, diagnosis). Which of those a form asks is a choice about the form.

Which one to three is your choice, not this page’s. Whether you keep the same fields from one entry to the next, or change them, is a choice about the record too.

A label can name a thing or name a judgement. Pain, tired and what I could not do today name a thing. Overall wellbeing and symptom burden name a judgement about several things at once. They are two different questions, and which kind a form asks is a choice.

The answers divide the same way. A number means what you decide it means, and it means the same thing in two entries only where you used it the same way in both. A word you already use carries its own meaning with it. Neither is the correct kind. Separately, the NIA advises being clear and concise when describing symptoms to a doctor, which is advice about talking to a doctor rather than about designing a form.

A form has no minimum length. One line, such as back all day, cancelled the shop, is a complete entry rather than a partial one. A longer entry has more words in it. Neither says how much of the day it accounts for.

An entry can also be spoken instead of typed. A voice note changes how the words get into the record. It does not change what they are.

And it can be written on the day it describes, or later. A same-day entry records that day; a later one is written from memory of it. Those are two different things to have afterwards, and this page does not rank them.

The fourth choice is the one that is easiest to get backwards. When you cannot remember a field, leaving it empty keeps the record true. Filling it in from memory produces a value that looks exactly like a recorded one and is not.

A blank is not a missed day and not a broken streak. It is one field you did not answer, on a day you did record.

• Length. Three fields is fewer than eleven. That is a count of fields, and it is all it is.
• Wording. A concrete label names a thing; an abstract one names a judgement. That is a property of the words on the form.
• Input. A spoken entry is spoken and a typed one is typed. The words that end up stored are the same kind of thing.
• What gets stored. A blank field stays blank, so no guessed value is stored as an answer.

• Not treatment. A form is not a therapy, and none of these choices is a treatment for anything.
• Not a change to your thinking. Nothing here improves concentration or memory, and this page does not claim that it does.
• Not a diagnosis. A short record does not say whether you have fibro fog, fibromyalgia, or anything else.
• Not a cause or a trigger. A shorter record still holds what you wrote beside a date. It cannot show what set a symptom off.
• Not a rule. These are four choices. Making none of them is a legitimate answer.
