I underwent a spinal surgery plus instrumentation two months back. I did not have any problem with my stitches and they healed well.
After two months, suddenly I had some burning and itching sensations from that area and I noticed a white color on my stitches. As days passed, it bulged and swelled and now it's soft, filled with pus, very sensitive to touch and the red color is also there.
I am applying betadine lotion plus betadine ointment to prevent the infection. Please help me. What is it? Is it a keloid or a hypertrophic scar?
