As reviewed below, the source of your problem is most likely to be, with about 90% certaintly, either a suture or delayed healing.
If it is the former, it may require removal. This is typically a minor procedure.
If it is slow healing, it may take some time, usually 3 weeks with wound care.
However, this is just my opinion based on frequently performing the procedure.
Definitely discuss this with your surgeon and feel confident that it can be managed.
In brief, I hope this helps confirm what the others have said,
