3 years faffing around with adult onset asthma (not convinced) and hacking, rattly, congested cough that makes me retch, I am finally going for more tests to try and find out EXACTLY what I DO have instead of my g.p's just fobbing me off. Consultant at hospital thinks it may be Bronchiectasis - not like I suggested that 2yr ago to my g.p's and was laughingly derided! Anyway, just at the end of another 7x day course of anti's and steroids for yet another chest infection but am booked for a Ct scan in 7x days time. Will anything be detectable after the course of treatment? Have I shot myself in the foot? Should I have taken nothing until AFTER the scan? Any advice welcomed thank you.
