difficult child has had trouble breathing lately. Today, his second day back to school, he said his chest was tight and he had to put his head down on his desk, and his sinuses were tight, and the feeling came and went all day but mostly, it stayed constant. He said he just can't breathe. husband thinks it's allergies and stress together, but not asthma. I gave difficult child some decongestants and 1/2 a clonidine about 10 min. ago. Any ideas?
