Hello,
Thank you for your query at DoctorSpring.com
I got the image that you sent and it does look like the stitches are tight and that is leading to a localized edema, around the stitch area. It looks white since because of the stitches, the blood circulation is getting hampered and the area is turning white. It's definitely not infected and that is an encouraging sign. There is just localised edema, and that will subside once the stitches are taken off.
Please consult with the doctor who put the stitches. He can take one or two off and it will become loose.
Once the pressure is removed, then the bulges will come down.
Feel free to discuss further,
Regards.
