Don’t want to criticize ya Ryan, you are right on just about everything you said but you may need to research a few more things concerning your asthma. As such, I can only assume that your asthma is not severe. Hopefully that is the case.
Difficulty inhaling and wheezing are indeed symptoms of asthma, both however are a direct result of the real culprit, which is the inability to expel CO2 from the lungs due to muscle spasms and constriction of the airway.
The inability to take a deep breath is the result of not being able to expel the air already in your lungs (you cant take any more air in if you dont have the lung capacity).
Do you experience coughing prior to when you have these asthma-like events? That might be indicative that it is related to acid reflux. As suggested, I would look at your diet for awhile. Might also look at any allergy triggers that may be present. I didnt catch that you experience any wheezing. That also makes me shy away from an asthma diagnosis.
I have never heard of any asthma medications that contained caffeine, however, there are a lot out there. Maybe Ryan is referring to over the counter medications like Primatene Mist (which I highly advise against by the way).
I currently take ALBUTEROL (Ventolin) and Advair. The albuterol is a fast acting relief inhaler and is relatively inexpensive (depending on your insurance copay). If you can swing some sort of sample from your doctor you may experiment with its effects. The advair is a preventative and theoretically should eventually lead to you not requiring the rescue type inhalers. It is very expensive if you dont have insurance.
In the past, I have also used Theophyllin pills, Vanceril, Intal, Serevent, Pulmacort, and a couple other inhalers that I cant think of right now. All with varying success. The combo I have now seems to control it the best.
While adult onset asthma does occur, I doubt that you have it.
You can do your own internet searches, but here are a couple articles I have found interesting…
