I can tell you responsibly that it's okay. The white suture you mentioned should be the newly generated muscle tissue on the wound, because we know that the original muscle tissue must be attached around the mucous gland tissue removed during the operation, so the wound will always feel swollen. In addition, don't always think that it can be removed in about 7 days, return to normal in about 3 months, and basically fade in 6 months.

I wish you a speedy recovery.
