During the first few weeks following surgery, it's not uncommon to experience backache and abdominal pain. You may have brown discharge for the first while. This will eventually change to a creamy white. If your surgeon has used soluble stitches, these will dissolve and pass out of your body. Otherwise, you will have to visit your surgeon to have them removed. Sutures are usually removed as part of your first follow-up appointment, normally within 7 to 10 days after your surgery.
