How is it diagnosed?

The diagnosis of HSP is made by looking at the signs and symptoms.  There are no special tests for HSP.  Blood and urine tests are done to see how the kidneys are working.

How long does it last?

HSP may last about 4 to 6 weeks.  The skin rash, stomach pain and high blood pressure may last for several months.  The rash may fade and reappear over this course of time. 

How is it treated?

• Rest.  Have your child take it easy for a while.  Your child should lie in bed or on the couch for two or three days.  Quiet activities such as reading a book or playing a card game are okay.
• Activities such as running or jumping are not okay.  Check with the doctor or nurse about what types of activities are okay.  Sometimes, your child will need to stay home from school.  The doctor or nurse will decide if this is needed. 
• Healthy eating.  It is important for your child to get enough good foods to eat and plenty to drink. Talk to the doctor or nurse about what type diet is best.
• Pain control.  Taking a simple pain medicine is often helpful.  The doctor or nurse will tell you what medicine your child should use, how much to take and when to take it.

What are the complications of HSP?

Sometimes kidney problems may become chronic.  Chronic kidney problems need to be followed by your health care provider.
