I guess the first thig would be chat with your doctor and get diagnosed or not. What to expect is different for everyone, just depends on each individuals needs. Early stages you might get some meds, inhalers for ER use, Inhaler for "maintaince" and recommendation to seek pulmunary rehab. Avoid things that bother you, smells, chemicals, smoke of any kind, exhaust from vehicles etc.... Please see your doctors though the sooner of knowing is better then the constant wondering.
