Does anyone have seasonal asthma at all ? I'm wondering if I maybe do. From June till October I had on/off symptoms of heavy chest , very unproductive cough, a whistle when I would cough and couldn't sleep because my chest felt heavy and felt like I just could not breath and when I would exercise it would get worse sometimes. My symptoms have finally calmed down so I'm wondering if this sounds like a seasonal asthma ?! I also did the methocholine challenge today but it didn't show anything but I'm also not symptomatic at this point.
