¡Recibí mi diagnóstico de HSP, pero la erupción no se parece en absoluto a las fotos, por favor ayúdenme!

so i got my diagnosis 3 days ago and I had big patches of painful swollen bruised purple spots. now as of yesterday all of the spots are black!!! I cannot find any pictures or anyone talking about their rash turning black. please if someone has ever had this help me out. its super painful and red all around the black spots. the black spots are also very hard and never broke the skin.
