My 4 yr old son has been sick since he was a baby, and every year he is getting worse. He has severe asthma, food allergies, and the past month he has been going into anaphylaxis shock for no reason. Beside these issues his specialist also thinks he has an immune disease. Every episode of anaphylaxis is worst then the previous one, I'm really worried and just feel helpless. Does anyone have any advice to a worried and sleepless mom?
