Your child needs to be evaluated by a Pediatrician
for treatment of Asthma. If it is mild and non-persistent,he should take inhaler/nebuliser therapy only during an attack of wheezing
. In case of severe and persistent asthma
he needs to be taking inhalers containing Sumetrol+Fluticasone
for a long time.Mind it they are quite safe and not habit forming as often preached by lay persons and doctors practicing Homeopathy
etc. Some of the preventive measures are:
1.Avoid exposure to dust, fumes and strong smells.
2. Avoiding Cold drinks,ice cream, candies ,chocolates and nuts like pea nuts and almond may help.
3. avoid contact with pets like dogs and cats.
4. use nylon or synthetic curtains and avoid carpeting of child's bed room to avoid exposure to house mites which are common triggering factors.
You need not be panicky. With preventive steps and proper treatment your child can live a normal life and may even grow out of it as he becomes older.
One more thing, the urine report shows Pyuria. Consult your doctor and preferably have a urine culture done.
Take care and lots of best wishes.
