Hi there. My 18 month old son had a cold in July and August. Late August, he deveolped a cough that wouldn't go away. It sounded EXACTLY like whooping cough. I took him to the pedatrican and she said it was probably asthma. He would wake up at night, cough really hard, cough with laughing and running. She ordered an x-ray and gave me a prescription for him which was Flovent.
The x-ray 'showed' asthma and an infection. He was on antibiotics for 10 days and supposed to use the Flovent for 2 weeks, and she then said hopefully this is a one time event. I should mention that 5 days before he started on the meds, he stopped the 'whooping' cough and didn't wake up from coughing.
Next week he caught my horrible cold and cough, went back to pedatrican for his 18 month check up.
She said it could take another 2-3 weeks for the cough to clear up, if not, come back and 'maybe she missed something'.
It has been 2 weeks, and the cold sounding cough, (productive) has gone, but not his cough. He doesn't wake up at night, mostly in the morning, and sometimes with laughing. We could be out walking for 2 hours and he won't cough for a second, but sit down at home and start.

My question is, do people with Asthma always have a cough? It doesn't really bother him and he has no wheezing, shortness of breath, etc. I don't know what could be triggering this, (we do have a dog, poodle) I vaccum 3-4 times a week, dust, etc. Or, should he not be coughing at all? As of right now, he is only supposed to take his medication until his cough clears, and with the onset of colds.

I really do appreciate any advice from someone who has asthma, or knows someone who does.

Thank you,
