My grandson, 14, began with a cough, shortness of breath. Then he began to have swollen glands in his neck and under his arms, and his legs are swollen( edema) and purple when he sits or lies down. When he stands up the legs become more normal color, but he becomes dizzy. He is going to another doctor tomorrow (he has been to the emergency room and to his pediatrician) to see if we can figure out what is wrong. the pediatrician says it may be a virus and to give it another week. The boy had asthma as a baby, but has not had an attack for a couple of years. He does have an inhaler if needed. He has been prescribed a Z pack, and now is on another antibiotic (I don t know which, but it makes him nauseated).
