tonsilolliths

Hi, I've only very recently started suffering from Tonsil Stones. Having a pretty bad case (6-13 stones on both sides every 10 days or so) and significant crypts, I was hoping to get CO cryptolisis laser done soon, perhaps in January. I live in the US and fly back and forth from Israel. My questions: Does the laser procedure hurt, and how long after can the procedure can I safely fly back to the States? A third question: my tonsil stones attacks began after spent a summer cat-sitting an apartment for friends and worsened considerably once I moved to an apartment with 2 cats. Could this possibly be related? thanks so much for any feedback, Carmel
