Bubbly feeling in lungs?

[Tella]

Does anyone have that? Like there a bit of liquid. I feel it when laying flat esp on my sides. Docs can’t hear it thru stethoscope. Weird!!! I can hear the sound of bubbles/scratching when I breath in and out. Thanks

I get this. Normally it is in the middle of the night when I have a bout of insomnia. Sorry, I have no clue what it is or can offer any insight. It is annoying as heck! Normally it clears when I'm upright.
