I had a stone in my saliva gland, but I think they are very different from yours, mine would swell whenever I was hungry, and ache in the same way as mumps do. It got bigger and bigger, I made an appointment with my gp, but n the day i was due to go I felt a pop, and my mouth was suddenly full of very salty liquid, this went on for about 15 mins, I still went to see the gp, and he said it was all the saliva that had been backed up eugh, he said it could come back, but if i thought it was the best thing to do was suck lemon drops, he said the acid in them disolves the stone, don't know if it works for tonsil ones though
