I swore but won't do it here because you're a gentle soul
"Tapping" - it's a physio exercise. You cup your hand and tap onto yur lung area to loosen the phlegm and cough it out.
And I used essential oils / homeopathic stuff on top of this.
Echynacia (sp? but on the go) burner and Eucalyptus etc - perhaps google which have anti-bacterial qualities and sit in hot bath; door closed and breathe that good stuff in!
I know Oregano oil does this but could not find it and used another one(s).
Colloidal silver for a few weeks to kill goggas
Old school Vicks and a towel over your head will also help! Brilliant.
Check with your doctor for advice.
And triple Vitamin C - water or you can get kidney stones.
Garlic out the wazoo (natural anti-biotic)
And tumeric in yer tea (natural anti-inflammatory)
And rest.
Nothing worse than being unable to breathe. Awful feeling. Been there often. You CAN recover <3
