Hello all, saw another physio this morning who gave me a really good method to shift mucus from the two bottom lobes:
Lie on one side with head on pillow ensuring top arm, lying along body, and shoulders are relaxed (I put my underneath hand on the top ribs to ensure breathing correctly - shout if this is not explained well). Take three slow, deep breaths ensuring you are breathing from the bottom of your lungs. Relax for a short while and then do three more breaths, slow and steady getting air deep into your lungs, trying not to cough (swallow cough if possible). Then do one long huff. Repeat process for ten minutes.
Then do the same for ten minutes on the opposite side - the lung on the top is the one that clears each time.
This method has been the best so far for me so keep some tissues handy as bought up loads. The physio said that if I clear properly I should not be taking antibiotics at all. She is also writing to the consultant to suggest he gets me a salt nebuliser to dilute the mucus and make it easier to bring up. Going to see her again in four weeks to check on progress but feel that appointment was well worth the money.
