Important: How to do the glass test

  1. Press the side of a clear glass firmly against the skin.
  2. Check a few times to see if you can still see the spots through the glass.

If you have darker skin, check paler areas like the palms of the hands and the soles of the feet.

What happens if you have HSP

There's no treatment for HSP. It usually passes in a few weeks and you can usually just rest at home until you feel better.

HSP cannot spread to others, so:

  • your child can return to school or nursery when they feel well enough
  • you can go back to work as soon as you feel up to it

Treatment to relieve your symptoms

Paracetamol can help ease any pain.

Do not take ibuprofen without speaking to your doctor because it could harm your kidneys.

Regular check-ups for kidney problems

You'll have regular check-ups for 6 to 12 months to check how well your kidneys are working.

You'll usually be asked to provide a sample of pee and have your blood pressure checked at each appointment. This may be done at home, at your GP surgery, or in hospital.

Treatment in hospital

You may need to go into hospital if HSP affects your kidneys.

In hospital, you may be given strong medicines like steroids to help ease your symptoms.

Long lasting effects of HSP

Most people with HSP make a full recovery. Any kidney problems usually get better without treatment.

But sometimes HSP can be severe and last several months, particularly in adults.

There's also a small chance the kidneys could be permanently damaged (chronic kidney disease) . This is why it's important to have regular check-ups.

Important: Getting HSP again

You can get HSP more than once. Get medical advice quickly if the symptoms come back.
