My child was diagnosed with fifth disease a few days ago. I also developed a lacy rash on my arms. The rash lasted a few days and a few days later, I began to experience severe itching from head to toe. I also experienced swollen hands and feet and joint pain a week after the rash. All my symptoms have subsided, except the itching, which has now lasted for 11 days. Could this intense itching be a symptom of fifths disease? And how long do fifths disease symptoms typically last in adults?
