Hi there. I have been to doctors almost every other yr. regarding breathing problems. They always say it's asthma. I finally accepted this, I think.....what I am doing now is, when I lay down to sleep, it feels like someone is sitting on my chest-when I do inhale, it's as if my chest/lungs will not expand. This seems to start at night but worsens when I go to bed. I too have been given different inhalers, but like "LouAnn" said, they all give me the shakes-I've tried: proventil, ventolin, azmacort, etc. What I am wondering, does this sound like asthma(to all u familiar with it) and advice on medications. Thank you.
