Hi all I have Been on doxycycline for 2weeks now as that is what my sputum result came back to take. Dr said it was a bug I had beginning with H can't remember the name. Just taken my last tab and still feel chesty and still have not a good colour sputum. I have been there before many many times all different antibiotics but as soon as I have finished them give it a week or so it's all back again. I really do not know where to go from here. I know I have severe copd but I know I could be better. My copd consultant put me on co amoxiclav which after I stopped taking them it all came back again. I have also had the azthroymyicin every other day without success. Anybody got any ideas what I can do, I do have another appt with my copd consultant next month. Also have been to PR for the last few weeks which I can't seem to manage to do very much before I can't breathe. I also have a exercise bike that I go on regularly for maybe 10min at a time. I really get so frustrated as I just don't know where to go from here. Hope you are all well take care.
