I have had multible barium swallows in the course of getting a fill. Everything looks normal. The port is filled to a very high level and I feel like it is fairly restrictive and don't eat for 4 days. Then I try something and it goes right down. I had a fill last me over a year and a half and it was never this difficult to get to the sweet spot.
My question still remains, how do you tell if the port or connection is damaged? Would that show up in the barium swallow? If it is not damaged, why is the Fluid not there after a few weeks? Could it be that he is not really hitting the port in the first place?
