There are 2 types of Asthma. One that is better in the cold, and the other not. My friend has Asthma, and feels better after she sticks her head in the freezer. I had to leave Alaska after 16 years because the cold made mine flare up bad. The kind I had/have is better in the high desert where it is warm and dry. Humidity has a lot to do with what kind of Asthma you have also. I cannot be in a humid environment at all. To where the opposite is for someone with the other type of Asthma.....humidity helps. If your in Florida, it's basically humid there right? Maybe you need to be in the high dry desert somewhere.
Unfortunately, Asthma is like some other things that can go into remission for no apparent reason at all, and you feel like your cured. Then, something triggers it (maybe stress....they don't really know), and you have it again. It happens all the time. I had Asthma as a kid, and then it was gone for years until I hit my forties. It came back hard. I thought I had outgrown it, but it was just in remission. I had it for a good 15 years, and then it tapered off again. Unless I'm around allergy triggers like substantial dust, pet dander, mold, etc. (my own things I'm allergic to), then I can live almost symptom free.
They are making such leaps and bounds in the Asthma field, and there are some really good meds. out there to help now. I have a Nebulizer that I used everyday at one time. Now it sits gathering dust, but who knows when I'll need it again. If you can get to an environment that is good for you, and remove as many allergy triggers as possible, you can greatly reduce your "attack" quota. Stop smoking if you do. You probably don't. Look into changing your diet also. From one Asthmatic to another, hang in there. I've had it so severe that I've had to take 4 back to back Nebulizer treatments at a time, ended in the emergency room numerous times, and spent nights in the hospital. The meds. can cause some kwirky side effects like changes in your personality, so keep that in mind. Try not to take to many steroid laced meds. if you can. Sometimes it's necessary to use steroids (Prednisone anyone?) as they are the only things to reach into the deep lung tissue, and heal the inflammation there if you find yourself getting worse and worse.
If you know what your allergies are, pick up a good allergy medication that can help. While Claritan is like eating candy for me, Zyrtec works amazingly well to keep indoor/allergy triggers in check. Allergra made me want to climb the walls and kept me in tears all the time. It's trial and error until you find what works for you. Sometimes the solution you use for your inhaler needs to be switched to see which one works the best. Only you know what your body is accepting or rejecting. Your Doc needs to be flexible and aggressive about treating you. If not, find a new Doc. I had to....twice.
If there's anyway I can help you....just ask. I'm praying for you.
