had my chest xray results today I've a chest infection. Since feburary I've had a cough, costronditis and now an infection. Got to take erythromycin 4 times a day. then go back in a few months for another chest xray. I'm glad I know what's wrong finally, my chest has been killing me for four months. Can a chest infection be passes on, my friend who's also got asthma stating getting really bad yesterday he must have taken is reliever 3 times in the space of couple hours. I hope I didn't give him an infection.
