What it is
It usually gets better on its own within a few weeks. Rest and pain relief help.
Sometimes it affects the kidneys, so urine and blood pressure checks are usually done for several months afterwards.
Common signs
- Raised purple or red spots that do not fade when pressed, often on the legs and bottom
- Painful, swollen joints
- Tummy pain
- Blood in the pee or poo
How it is usually diagnosed
- Examination of the rash
- Urine tests
- Blood pressure checks
- Blood tests, sometimes
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Urine test results over the following months
- Blood pressure readings
- Paediatric letters
Questions to ask your doctor
- How long will urine checks be needed?
- What signs of kidney problems should I watch for?
- Can it come back?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A rash that does not fade under a glass with fever or a very unwell child, severe tummy pain, or blood in the poo: get urgent medical help
