I was diagnosed with Bronchiectasis about six years ago.I have had virtually a permanent cough producing a lot of mucous. I have always been a runner and running has certainly helped me to clear my lungs.About three weeks ago while out running I was bitten by a dog .My doctor immediately gave me a tetanus booster injection and gave me a course of Augmentin antibiotics.Since then I have hardly coughed at all and my lungs feel quite clear . At night for the first time I can lie on my left side without coughing. I have of course had many antibiotics in the past but never with this effect. Perhaps it was the dog!
