Stitch infection 7 Months post-op?

Hi there, Thank you for your question. If you are having new redness, let your surgeon know. It is always best to be seen by your surgeon when you have a concern. You may have a hypertrophic scar which can be treated with a steroid injection.Best, realdrsix

It is impossible to say without knowing which kind of stitches were used, if they were dissolving or not.  It potentially could be a stitch, but you should visit with your surgeon to get examined.
Scars will fade over a year, sometimes two years.  When scars start out, they are pink, firm, and raised for several weeks in some cases.  This is because the collagen that is forming is immature and filled with microscopic blood vessels.  Over time, the collagen remodels, and the scar will become more pale, flattened, and soften.  Small ridges will flatten as well.  During this first year, it is important to protect the scar from the sun as any sun exposure can potentially permanently hyperpigment the scar.  As well, there are adjunct scar treatments such as Mederma, silicone scar stickers, and potential laser treatments or steroid injections.  These would need to be discussed with your plastic surgeon depending upon your specific situation.
 Best of luck!
