Hi, I have had a recurring chest infection which began in January, lasted three weeks, back on my feet and three weeks later, back again. I am just finishing my antibiotics and steroids today and am still finding my lungs are filling with mucus. This is new for me and has never lasted like this before so I dont know whether I should begin walking out in the park again (very gently as I am really puffed) or not. I have moderate COPD and am normally quite fit walking the dogs every day for 2/3 miles and last infection before this year was January 2016. I would be grateful of any advice, thank you.
