I was diagnosed with asthma when I was 8, since then I've been fighting with the nhs (I'm now 26) because I didn't believe it was a correct diagnosis. My only symptoms is a really bad and persistent chesty cough. I've now been diagnosed with COPD and my cough has been getting worse every year. I dont and never have smoked which is apparently why it was so hard to diagnose me. I'm scared about the future of this condition. Please can any one tell me what to expect?
