After the surgery, my armpit area was a little itchy and the upper band was tight, but I thought it was because of the stitches and ignored it, but that's what happened...
 I contacted the manager in charge and he said it was like an allergy to the upper band, and that it could happen if you have sensitive skin. It was so sore and painful. I'm worried, I'm really sad, and I wonder if the surgery was for no reason... Are there people like me? ㅠㅠㅠㅠ Ha, I'm really so sad.
