How long does this disease take to completely go away?
The major initial symptoms (acute illness) of Henoch-Schonlein Purpura (HSP) usually last about a month. These symptoms generally include rash of the buttocks and lower extremities as well as joint pain and swelling.
Longer-term effects of HSP can result when the kidney is damaged from the illness (permanent damage is not common--less than 5%). Patients older than age 5 years are at higher risk of kidney effects of HSP.
HSP can recur in one third of children affected. When HSP recurs, the effects are usually milder than the initial symptoms.
