Salivary Duct Stone Remedies

I recently had that "tiny tube" surgery someone mentioned and IT DIDNT WORK. My stone is 4mm and is creating blockage. Recovery from the surgery sucked, I was on a liquid diet for two weeks because I had stitches in my mouth. The doctors want me to now go in for another surgery and get my whole saliva gland removed. I am going to try all these home remedies prior to going in for another surgery because the last one didn't do one thing except created more pain.
