For years I had painful mouth sores as a result of herpes simplex virus 1. I would get them every winter and we just go on and on it caused lots and lots of pain and discomfort
Finally I did completely cure it with a rife machine using specific frequencies that target the DNA of pathogens. all took was a few treatments, and boom, that was it. Of course I can't guarantee you're going to have the same experience.
The problem is that rife machines are very expensive. One thing you might consider is see if anybody in your area has a machine that they're willing to let you use or borrow for a fee
