I finally got so fed up with it, I went into the bathroom and got some small manicuring scissors, poured hydrogen peroxide on the scissors and snipped the end of my salivary duct! The excess fluid squirted like a unkinked hose!
Then I rinsed my mouth out with hydrogen peroxide/water/himalayan salt several times and I have been 'right as rain' ever since ... no more stones, no more blockage.
Doctors are mostly m*o*o*ns who only know how to throw drugs at you. [The exception, as I recently experienced after my hubby's heart attack, are EMTs and ER docs!!! Emergency medicine is top notch, it's just the everyday stuff that the 'regular' docs can't figure out!!]
