Good morning Welcome to our asthma community. It must have been a relief to go so long without any asthma issues. I'm sorry to hear that you recently had an asthma attack after such a long respite.
To address your question, once someone is diagnosed with asthma, it typically remains a part of their life. However, there are instances where asthma seems to go into remission as we age. This can lead to extended periods, sometimes even years or permanently, where asthma symptoms are minimal or nonexistent. While the exact reasons for this remission are unclear, it may be attributed to changes in airway sensitivity or avoidance of triggers that once exacerbated asthma symptoms.
As you've experienced, asthma can resurface unexpectedly. It's possible that you were exposed to a trigger that had been avoided for many years. Determining the exact cause can be challenging, but discussing your specific situation with your doctor, who knows your medical history best, may provide insights.
Regarding your second question about managing day-to-day life with asthma, here (https://asthma.net/living/10-tips-for-obtaining-good-control) is an article I wrote that you may find helpful. It talks about how to obtain good control. But those tips will also help you "maintain" good control -- and once there (as you know) you should be able to do most of the things you enjoy -- despite having asthma. What do you think?
