First of all, I think pinching is useless unless you are young. . . My method is to knock (listen to what others say online and try it yourself), especially between the eyes and the most prominent point on the bridge of the nose. The method is to knock into the middle of the nasal bone with a hard object. Don't make a mistake, just knock until it hurts. Keep looking for a week, it will get higher, just don't overdo it.
