I developed double wrinkles on my back, so I did dual training for the first time and the swelling on one side seems to have gone down, but the other side is like a sausage, whether it's the swelling or the line is wrong. How can the swelling be like this on the 5th day even though it's not an incision but a burial? ㅠㅠㅠㅠ I'm so confused.
