Did this start when you moved to this residence? Could be hidden mold causing allergy coughing. My husband has a horrible dry cough. Its most likely do to the mold that we cannot get rid of. You should get him tested for allergies, it will be the only way to find out whats causing it for sure and then you can medicate accordingly. Also, try putting a cool mist humidifier in his room, or get a big one for the house to keep some moisture in the air. Don't get a warm mist as this can cause bacterias to grow and you definitely don't want that. If you can't get rid of the carpet make sure you vacuum daily and get some hepa vacuum bags. Mini blinds are better then curtains because they hold less dust. Also, change the filters in your ac/heat unit to allergen filters this will help too. Keep the dust minimal. Use a damp cloth to dust rather then a dry one. I could go on about things that will help with controlling indoor allergies, but it's best that you talk to your doctor! Hope this helps, oh and, Dr. Sheth is the best Pediatrician in the Park. He is directly across from Walmart on 235.
