Since I was 36 am now 73..have been on asthma medication,nebulizer,inhalers...it's been rough. I have been asthmatic free for 3 months, no meds at all...I went off of everything and I feel fine.Is this normal for real asthma.? I am now seeing a cardiologist for a heart problem that I never knew I had, could problems with the heart (vascular system) mimic asthma?
