Since my son was 2 he experiences red face with white around the nose and mouth along with shortness of breath. We have been told allergies but NO, asthma NO WHEEZING. He is now 6 and can just barely walk fast with feeling sick and short of breath. His face gets redder quicker and no one seems to know. We have also been told he was over weight at 4 years old but now is tall and skinny. can anyone help us? I feel in my heart that something is not ok.
