To be fair - everyone's symptoms are on different levels, so the answers (if there is one!) could be many. I am only speaking from personal experience here however, I had countless endoscopy's when my doctors were trying to figure out what was going on, then barium swallow which assisted greatly with the final diagnosis. Then came the Oesophageal Manometry (only have one child but would gladly have another instead of having that treatment again!)
After which, 2 dilations (30mm & 35mm balloons) neither worked immediately and I still suffer but not as bad as NOT having any of the above (minus the childbirth!).
That all being said everyone is different, with different levels - if you find a treatment that works for you, good for you!
