Henoch-Schonlein purpura (HSP) makes the small blood vessels in your body swell. It can cause a red or purple rash on your legs and buttocks, joint pain, or belly pain.
Often the cause of HSP is not known. Sometimes it can be caused by another illness, such as a cold or virus. Some foods, or even an insect bite, can also trigger HSP.
Most of the time, the rash and joint pain should go away within a few weeks. Belly pain will likely go away sooner, within 3 days in most cases.
