I have asthma in the day. It becomes terribly unbearable during the day and there is no set pattern or time that I can have a flare up. I have it on an allergen, or a low pollution, or a good barometric day. No matter what I do to prevent it, I have flare ups so often irrespective of where I am or what I am doing. Is there anyone else on this board suffering like me? I am just curious to know.
