DD is just 6yrs old. We spent last night at the hospital where they have diagnosed HSP though she is home now. Her legs are covered in the purple non fading bruise type spots and her knees and one ankle are very swollen and sore. So far kidneys are good. Would love to hear how others have done from this point. How long does the rash stay, how long will she have sore legs. Did you deal with kidney problems? We are especially concerned about potential kidney issues as she had to have short term dialysis as a toddler when she had septicaemia and was very poorly. Until now at least though they had been doing well and we hope this will continue from here.
