Hi Brittany and List, At the risk of being redundant I'd would generally concur with the respondents to this topic. I have been a relatively severe asthmatic for over 30 years and if anything, playing the horn has definitely helped my breathing. That being said there seems to be something else going on here. First and foremost, let me disclaim I am not a doctor nor do I play one on tv! What I'm telling you is from my own experience. Albuterol, the generic name for Proventil and others, is used as a "rescue" inhaler, that is, you generally use it to force open the airways once an attack begins. Also, albuterol is usually prescribed in conjunction with an anti-inflammatory and an antivasalconstictor, either in the form of pills or inhalers, examples of the inhaled form include Flovent and Serevent. There are some new inhalers on the market as well. It would probably be a good idea to discuss a treatment program soon. Also, it might not hurt to get a second opinion from a pulomonologist as well. Another piece of the treatment puzzle is to discover what the triggers are for your asthma. Some of mine include(d) exercise and animal dander. As for exercise, during the first few minutes (as much as thirty) of vigorous exercise would trigger the beginnings of an attack. If I really felt like I was in trouble, I would use the inhaler, but generally after a few minutes, the paroxysms would subside and I would continue with my exercise. As for allergens, you will need to find a way to deal with them. Molds can be one of the worst allergens around. Since retiring from teaching and now working in the museum field, molds are a very hot topic. Some very benign looking sources can carry spores of some of the most deadly molds, especially if they are ones to which you or others might be highly allergic. Keeping your mouthpiece, mouthpipe, and case clean are paramount in this regard. Again, this is a topic you will want to pursue with your physician and/or a pulmonologist and you'll want to do it soon. Best wishes for happy horn playing.
