It started a a couple yrs ago to burning, and stabbing to the point of having to drink a lot of water and lay down til the pain in chest would go away. Diagnosis gird,  In the last few months I have been in and out of hospitals, and doctor offices. I am losing a lot of weight, I can not breath when I eat or drink.  I keep very little down, and everything comes up as balls of flem, mixed with foam, no acid or vile.  It is sometimes painful and worse of all I can not sleep and getting to the point of being afraid to go to sleep.  I wake up with either bed covered in slime, and this happens if I am sleeping on side and it drains out of mouth. If I am on back i wake to gasping, gagging and fluid exasperating as I am trying to hold what I can back to get to restroom. I now just have a bucket near me at all times so I can let it go into that.  I can continue but I think I gave the major details to hopefully get some kind of answer. I only wish I could have insurance so they can get this taking care of.
