I have 40% lung function since Covid. My pulmonologist said suck it up buttercup. My Oxygen levels are around 94%. I have a fantastic Phsyio. I get 12 free maintenance visits per year to my physio.
I am on sereflo, theophilline and forvent. I weaned my self off cortisone and am not and will not go onto oxygen.
I had a coughing fit 6 weeks ago, not knowing that I have Swine Flu, and popped 3 discs in my lower back. My sats still hovered at 94%. I had to wait until my lungs got better, 2 weeks and had the op. Life has its ups and downs.
Perhaps your lower oxygen levels are may be weather related or is there a lot of pollen around.
I went onto Trilogy briefly, that took the place of Sereflo and Forvent, and found that I was suffering with my Oxygen levels. Went back onto Sereflo and all is stable.

Have you ever tried a supplement called clear lungs it's a herbal supplement on Amazon my son said when they were sick him and his kids took it and clear their lungs fast my son suffers from asthma since a baby and it helps

I also found Sereflo works for me Doloris🙌🏻

Not everything works for everybody and I feel my lungs is much better now that I am using my sereflo pump correctly. My homeopath told me he would not tgive me any medication as there comes the stage where you need to use western meds. Keep sttrong Doloris

Hi Linda, the Pulmonologist whom I see does specialize in Pulmonary Fibrosis and he has tried a very expensive medication, for Fibrosis, Esbriet, on me, but it does not do very much for me. I do daily breathing exercises, but the Pulmonologist is very careful about exercises, because I had a collapsed lung two months after my initial stint in hospital with COVID and he's scared that the scar on my lung might open up again. I am not on oxygen, but do have a portable oxygen concentrator and a oxygen cylinder just in case I need it.
