thanks everyone for your prayers. After having the pneumonia in late May, I developed a cough that never left. Had a chest xray which is leading me to getting this scan. Either it's chronic bronchitis or COPD.The pulmonologist seems to think it probably isn't COPD but wants to be sure. I went to the health food store to find comfrey tea but was told it isn't produced anymore. The clerk sold me a bottle of mushrooms to help boost my immune system. who knew? my daughter eats them on a regular basis for that reason. I'm behind the times, haven't been keeping up with my reading. i got tea for cold and flu to see if that will help. back in the day, hippies smoked mushrooms. I wonder if that boosted their immune systems.
