What you have described is exactly what I am getting out and exactly what mine looks like! The color, consistency (sometimes gel consistency) bubbly, foamy clear secretions and sometimes a mucus plug that came from lungs but this daily 1/3-1/2 cup of clear, bubbly sometimes watery, sometime gelatinous mucus seems to me to be coming from my sinus’s. I don’t have a hernia but I do have one CF gene mutation that causes thick sticky mucus. My CF pulmonologists however say what I am experiencing is not from CF but all the ENT, Allergy, Neuro, internists seem to just say, “ oh that is due to your partial CF.” Have you tested for CF with a genetics test and sweat test?
