Can asthma cause issues even when not having an attack?

A number of asthma questions here, actually...

1...Can an adult develop asthma within the first few months after quitting smoking?

2...Can asthma symptoms, like shortness of breath and chest tightness hang around even when you aren't having an attack?

3...Can those feelings be pretty constant?

4...Can someone who has asthma have anxiety and panic attacks even while not having an attack?

Yes, I am going to the doctor Tuesday afternoon to deal with the problems I am having. Just looking for ideas before then. So, anyone who might be familiar with onset of asthma in adults, please reply. Yes, I am trying to self diagnose, but only temporarily!!!

Thanks guys.

Asthma can develop at any time. I myself have adult onset asthma. Yes the symptoms can be lingering even if not having a full blown "attack". Without a bronchial dilator and a maintenance medication like singulair for example the symptoms can seem constant. Yes anxiety and asthma are two different things but can have similar symptoms such as the chest pain and shortness of breath from different etiologies.
