I have had life-threatening spasmodic breathing episodes for the last year. My GP attributed it to asthma, because that's what it looked like, and they have given me prednisone shots and later on, antibiotic shots, to control it (for about 6 weeks at a time). I have well-controlled type II diabetes, so predisone can cause it to go out of control fairly quickly. Prednisone also caused some occasional pain in my feet, probably because of the elevated blood sugar. All the asthma drugs they gave me actually made me sicker, like Advair, etc. Lo and behold, I was able to talk my doctor into a referral to an allergist, and my allergy numbers are off the charts! All grasses, most trees, and many animals were high enough to cause anaphylaxis, especially when surrounded by more than one. Anaphylaxis can cause the labored breathing I suffered. Meanwhile, I have the lung capacity of an Olympic swimmer. I have an elderly friend who has gone to the hospital several times this year with the same problem. After I found out my results, I talked to his wife, and they discussed the allergy and infection aspect with the doctor. Turns out he had fairly severe allergies and infections that made his life-long asthma go way out of control. With a medicine for infection, he is 10 times better - the asthma is under control because it is not being jump-started by the low-level infections he suffered. I don't even have asthma, it just looks like asthma. I will begin years of allergy shots, just like in my 20's. (I am 55). The upshoot? Some people are suffering severe asthma symptoms. Others have a combo of problems which are exacerbating the asthma-like problems. Doctors who think you only have asthma tend to only treat asthma. Prednisone greatly reduces inflammation, which is a common factor in all the above diseases. So, calming the symptom doesn't mean treating the source. You long-term asthmatics should also look inot taking allergy tests if it is considered safe (they DO inject a small amount of allergens in your skin), and not spend 100% of your time with the pulmonary specialist who is only looking at your lungs. Also, you really need to do some cause and effect testing with antibiotics or similar to see if you have some type of infection. My friend and I are both on our way to better health because we went beyond treating the symptoms.
