My son is 2 years old and has been sick off and on for 4 months now. A few months ago he started with a rash, peeling of hands and feet, red mouth, sore throat, fever for 3 days. He was tested positive for mycoplasma and treated with the z-pak antibiotic. After 3 months he started the same symptoms rash, low grade fever, cough and runny nose this time. treated again with z-pak. And now (only 2 weeks after the last sickness) he has had a fever for 3 days, bad cough, peeling of toes, hands and feet but no rash this time. Can you give any advice on what we should do at this point. He does has swollen lymphnodes all over his body including groin, neck, armpits.
