Hello. I wanted to share two experiences I've had this week with the Biotrohn. One is that he had a swollen gum from a tooth. It has happened to me other times and, normally, it took a week until it was cured. This time I used the Biotrohn and with just one treatment it went away in a day. On the other hand, due to a fall in the field, he had been suffering from muscle pain for 2 weeks and could not walk well. But I went on vacation and then I tried the fibromyalgia program and the next day I was walking for the first time without pain. I am delighted with the machine!
