I also don't suggest to do so. My son had this experience before and this really affects his psychological state a lot, I need to use a very long time to calm him down, and he has had a very very long time which he scared about the nurses and doctor a lot, of course, including the clinic or hospital-like feeling. He cried crazily everytime going to the clinics after this treatment. And I felt very "heart pain" when I saw the physio do the process......
I really don't want to have the same process again, it's not that useful...
