I looked up HSP because I've never heard of it before. This a quote I found on it.
Henoch–Schönlein purpura, also known as allergic purpura, anaphylactoid purpura or Vascular purpura and commonly abbreviated to HSP, is a systemic vasculitis (inflammation of blood vessels) characterized by deposition of immune complexes containing the antibody IgA in the skin and kidney. It occurs mainly in young children.
Typical symptoms include palpable purpura (small hemorrhages in the skin), joint pains and abdominal pain. Most cases are self-limiting and require no treatment apart from symptom control, but the disease may relapse in a third of the cases and cause irreversible kidney damage in about one in a hundred cases. The exact cause of Henoch–Schönlein purpura is unknown, although it may occur after certain viral and bacterial infections, as well as an adverse drug reaction to some medications.
I've had an allergic reaction to drugs before with bumps, but they didn't look like the pictures I saw.
I wish your child luck.
