COPD does not attack suddenly. Sounds more like an infection. For both infectious and non-infectious bronchitis it is extremely helpful to to take 1000 mg of vitamin B5 until the condition subsides. B5 is both a mucus thinner and an anti-inflammatory. There are no side effects. I have been taking B5 for chronic bronchitis for a long time. I also take 500 of vitamin C, another anti-inflammatory.
hi mgb.....yes that unfortunately sounds very much like copd.
