How to describe symptoms clearly, even on a bad day.
Updated: 23 September 2026
Describing a symptom out loud is a skill no one teaches you, and it's difficult when you need it most. The aim isn't to sound clinical. It's simply to be understood by someone who hasn't been living through your week.
Four things carry most of the meaning: what has changed, how often it happens, how long it lasts, and what it stops you doing.
Say what has changed, not just what hurts
A symptom you've had for ten years means something quite different to the person listening than one you've only had for ten days. Make it clear which one you're talking about.
"The pain is worse" is hard for anyone to act on. Something like "The pain has moved into both hands since March, and now it wakes me at night" gives them something useful to work with.
Put numbers in where you can be honest
Numbers don't need to be exact to be useful. A rough but truthful answer is better than a precise one you've made up.
Try counting in whichever of these ways fits best:
- How many days it happened in the last two weeks
- How many times a day, or a week
- How long it lasts when it comes
- How long you can keep going before you have to stop, in minutes, streets, or stairs
Describe the effect on the day
This is the part people leave out, and it's often the part that lands. A symptom that stops you working, washing, driving or leaving the house is telling a story about severity that no rating out of ten can tell.
"I'm tired all the time" is easy to nod at and move past. "I sleep ten hours, and I still couldn't do the school run on four days last week" is much harder to mistake for ordinary tiredness.
Use simple words for how it feels
If the right word won't come, just choose the closest one from a list and say it's the nearest you can get. No one is marking you.
Words people often reach for:
- Pain: aching, burning, stabbing, throbbing, gripping, raw, heavy, like a band, like a bruise
- Fatigue: drained, leaden, wading, flattened, running on empty, hit a wall
- Thinking: foggy, slowed, blank, losing words, losing the thread, can't hold a list
- Feeling in the body: pins and needles, numb, tingling, weak, shaky, hot, crawling
- Dizziness: swimmy, floaty, spinning, greying out, unsteady on my feet
Share the pattern, and leave the cause open
It's helpful to mention any patterns you notice. For example: worse in the mornings, worse before a period, worse for a few days after a busy day, or better when you rest flat. These details can be really useful.
Try sharing them as patterns rather than firm conclusions. Something like "It seems worse in the week before my period, though it might just be coincidence" feels honest, and it gives the person listening space to think. Just because two things happen together doesn't mean one caused the other, and saying that gently helps protect your credibility.
A few phrases you can borrow
If you'd like a gentle starting point, these kinds of sentences tend to be easy for others to understand:
- "The thing affecting me most is ..., and it has been worse since ..."
- "It happens about ... times a week, and lasts about ..."
- "On a difficult day I can't ..."
- "I've tried ..., and what happened was ..."
- "What worries me most about it is ..."
When the words won't come
If words disappear under pressure, try writing the four lines down beforehand. You can hand them over, or simply read them out. It can also help to ask for the reply to be written down too, because listening can be just as difficult on a bad day.
Keeping a short record as things happen makes all of this easier, because you're reading rather than trying to remember. That's the whole idea behind taluvu: write a little as you go, so the day you need to explain yourself isn't the day you have to recall everything.
Questions people ask
How do I describe pain to a doctor?
Say where it is, what it feels like in plain words, how often it comes, how long it lasts, and what it stops you doing. The effect on your day is often the most useful part, and it doesn't depend on picking the right number.
What if my symptoms sound vague?
Vague symptoms become clear when you attach a count and an effect to them. "Tired" is vague. "Ten hours of sleep and I still missed four days of work" isn't.
Should I say what I think is causing it?
You can say what you have noticed, framed as a pattern rather than a conclusion. Saying that something may be coincidence keeps you accurate and keeps the conversation open.
