I received it 2nd and 3rd time at a different place from the first hospital. The doctor who did the 2nd time did the procedure without much explanation, but unlike the 1st time, it was really so painful that I almost cried. It seemed to do it, but unlike the first, I had quite a few bruises from the next day, and I don't know if the effect was strong or because it was the second time, but it lasted and was good! In the 3rd session, I came and consulted on the area of concern, which side I focused on, and after consulting about that, I did the procedure, but the doctor didn't give pressure to my hand and it floated, so I couldn't continue to inhale when I was on the side of my nose, and I tried two or three times. It didn't feel meticulous. Maybe that's why, or maybe it's because the intensity has really weakened, there was little pain and no bruises. I'm not sure about the effect as it's only been a day, but I'm going to get it from someone else next time...
