I think it's still 2 months post surgery. There could be inflammatory reaction because of the sutures. It is possible so we need to see the pictures to evaluate it correctly and I think most of the times they dissolve by themselves. If there's no fever or any other issues, just you can wait for some more time for body to respond to the inflammatory reaction though active intervention is required.
Right now you can share the picture so that we can evaluate it better. still it's just 2 months old we would prefer to wait and watch. You can also visit best plastic surgeon in India for exact treatment.
