Cough Variant Asthma. I am so lost

This past winter my daughter age 5 at the time started to have constant dry cough. Worse when she would play and at night. She was then diagnosed with cough variant asthma and allergies. She was on a daily inhaler for the asthma and a neutralizer as needed and an emergency inhaler. She still had a cough not bad but it was there. When the weather started to warm up her symptoms of the asthma went away. She then started with saying her belly hurt. It was above her belly button, bellow her ribs. She threw up with it twice and would break out in a sweat. She would never cough or struggle to breath. We thought maybe it was acid reflux as her sister has that. But acid reflux meds didn't work. We then went back to her asthma dr and she tested for food allergies but they where all negative. When I told her I had stopped her everyday inhaler she was not happy. She said some children have attacks and say there stomach hurts when in fact it is there chest hurting. And said to go back on the inhaler. She has been back on it for about a week. And we had not heard her complain until tonight. She rain to the bathroom crying that she was going to throw up, breathing heavy and sweating saying her belly, and throat hurt. Not really saying her chest till I asked. I went and got her neutralizer and gave it to her. It took a while(like it normally does) but she finally said the pain was gone.

Has anyone had any experience like this. To have an asthma attack with no coughing, no wheezing(she has never wheezed), no trying to catch her breath, nothing like that just the pain. Please help me to understand what I am dealing with.

A couple possibilities come to mind...

She may be allergic to something in the inhaler that is not in the nebulizer solution.

She may be swallowing more than inhaling the inhaler medication, and then it may be making her stomach upset from swallowing the inhaler medicine...

So it may be safer for her to get daily nebulizer treatments instead of a daily inhaler...
