Personally, I had something very interesting happen to me when I was diagnosed with Addison's about ten years ago. Before that time, I had suffered with asthma for most of my life. I'd had some pretty severe attacks and used my prescribed fast-acting inhaler along with long-term medications to reduce swelling on a daily basis. But, along with the devastation caused by a very delayed diagnosis, I had a pretty cool, yet predictable happening after my treatment for Addison's began...my asthma attacks disappeared. The steroid treatment needed for Addison's helped my asthma symptoms to virtually disappear. I could breathe easy.
Often, I have wondered about other people with adrenal insufficiency and their experience with asthma or other conditions that were made better by treatment for their adrenal issue. So many other conditions are treated with steroids, so it may be more prevalent than I realize. Regardless, I have been so thankful for the long reprieve from asthma, thanks to my Addison's. Yes, life can be strange.
