I had my last one the beginning of December. After I start feeling better I start back with my exercise routine. Breathing exercises, as well as upper body workout, along with walks. I do drink mullein tea to help with the phlegm, and eat heathy food staying away from carbs.
You have been lucky. It is a learning curve as to what will help you best, trial and error. This is what has worked for me, exercise seems to be a key.

It can take a long time to recover from pneumonia if you have COPD. I found that resuming my exercise program as soon as I could without coughing myself off the treadmill, was the best thing I could do. I had to go back practically to the beginning and slow things way down, but it didn't take long to get back to where I had been before I got sick.

I go in Prednisone and Zithromax and it is usually fine within a week for me

I find that chest infections hit me quite hard. My last one was the worst I can remember experiencing.

Michael Zerjav. Thank you for your reply. I do attend a weekly Chair Yoga class plus also a weekly keep fit class. Sometimes that does effect me breathing wise. As my instructor has told me I cannot, during the class reach the level of exercise that I was at prior to my flare up. I also do all my shopping and go to the particular store, I do not use a delivery service so I end up carrying two bags of shopping lol. I realise I have to reset my life after the flare up and find the levels I can handle easily. Thanks again for your reply. Regards Dave Carter
