Yep, a simple plain Barium swallow showed all that - and it's so much easier than an endoscopy - which found zilch!
Next I go for a video fluoroscopy - this shows me eating food to see what happens with the swallowing problems, and I have been talking via email to a renowned Professor and he has recommended that I have the restech dual impedance test which will show if there is acid or alkaline coming up the gullet and into the mouth via a spray or gas which in turn may be causing all the spasms in the chest!
So more lovely tests to look forward to, but at least it's a step in the right direction.
Have you had a barium swallow or a ph study?
