Signs andsymptoms

The main symptoms of HSP are:

  • a skin rash (purpura) that looks like small bruises or reddish-purple spots, usually on the buttocks, around the elbows and on the legs, and sometimes also on the face and upper body
  • pain in the joints such as the knees and ankles, whichcan also become swollen, tender and warm
  • tummy pain , whichcan develop suddenly before the rash appears

HSP can also cause some other symptoms, including passing blood in your urine or stools, vomiting and diarrhoea .

The condition is often associated with a previous infection (see below), so you or your child may initially have symptoms of an infection as well, such as a high temperature (fever) and feeling generally unwell.
