I had a upper eyelid surgery done in June 2016, 6 months post surgery now. Initially it took some time for swelling to go off, and I noticed a stitch that it's being left inside and went to a local surgeon to have it removed. The swelling went down very soon. But the spot that the the stitch was removed started to have pimple that keeps coming back after removal. And also swelling of my eyelid that cannot go off, what should I do?
