Infected saliva glands and even stones are pretty common. Tumors are unusual and usually benign. Malignant tumors are rare and get you fast. The infection is real hard to control because of where it is located. My symptoms started with puss in the saliva and then pronounced swelling under my tongue and on my lower jaw. I got SICK. Antibiotics only slowed it down. The gland under my tongue abscessed. This let out puss, lime particles, and 24 small tumors. The abscess finally healed. For three weeks large quantity of lime have broken loose, dissolved, and come out with the spit. After enough junk came out there was room for the stones to start moving. Some were hard, but most were pretty soft and dissolved over a period of four hours. This problem can drive you crazy. Sharpen the points of a jack, put it under your tongue for five weeks. This is the only way that I can describe the harassment Ther is no apparent connection to PK. This is just part of the human condition. Of course PK makes treating this problem more difficult. In my case, none of the local DR`s would do the surgery. The wanted me to go to a major teaching hospital. My conclusion is if you feel better when on Antibiotics, look real hard for a hidden infection. George Campbell
