Hi , and thanks for sharing your story here in the COPD.net forums section. One of the classic symptoms of COPD (although this does not occur for every patient), is thick, inspissated mucus (otherwise known as 'sticky phlegm'!). As you may be aware, there are various approaches to the treatment of this particular characteristic of COPD - some work for some folks, while others work for other patients. It is a very individual type of treatment that varies in its level of success.
Do you find that the menthol (Vicks) and Olbas oil helps you? Does it seem to be effective? Have you discussed this with your physician?
I am sorry to hear that you endured a cardiac arrest and a collapsed lung, too. I am very glad to know that you are here with us. If there is anything further you would like to share with us, we will be all ears. As well, if there is anything we can assist you with, please let me or any other moderator / team member know. You are always welcome here!
All the best,
Leon (site moderator COPD.net)
