I'm no dr of course but could ut be asthma? They can test for it.

no, do not do bleach. I am asthmatic and trigger to bleach. It could be a few things, in my *puts a eye mask on red so she don't see post* Beep Beep Beep (now I'm an answering machine) it could be

Asthma - Respitory testing needing to confirm with , pulmonolgists (something like that)
Acid Reflux - Try having head and neck elevated (by pillow n such)
Allergies - Allergy proof rooom

Detergents, use something like for "sensitive" skin. Soaps, I personally think Jergen's rock, Personal Hygienge, I prefer Tom's Natural


Air filter in room

Doc can do allergy testing

Must be a stubborn virus or bacteria there.

I don't know if this is the same thing, but when I was about 4 I started getting these severe attacks of coughing, inability to breathe, and extreme mucus production. It would often strike at night and my mom would find me wheezing and completely blue. She would actually have to beat on my back to try and get the mucus out. My doctor diagnosed me with differing things (even walking pneumonia) when he finally settled on Asthma. Apparently there is a wet form. However, an inhaler would not work. The only thing that worked and saved my life was Theophylline. I sprinkled it over ice cream and took it every day. This was about 24 years ago, so they might have differing medications. Hope this helps!
