Ohana...I don't know if this is an answer to your question, but I found I had that lump in my throat/hard to breathe problem too. I was on Azmacort because it started to appear that I was asthmatic. I now think I am not. Since increasing my B12 and taking iron due to extreme low levels in both, I am not having the breathing problems. You were diagnosed with asthma and I am not saying you do not have it. I just wonder if you should check out your levels in the other areas. They may be causing your breathing issues. Stress believe it or not can also cause the same issues too.
