I had dialysis about a year ago, and I don't think I really felt anything like sagging. Since the bone itself has a skeleton, I don't completely like it even if I breathe. I'm worried about the outline. I don't know why my throat was sore for about 3 days from that day, but it was very painful and it was a little difficult to pronounce or eat. The swelling lasted longer than I expected. After 6 months, it looked natural as if I didn't have surgery.
