I had the TIF procedure in August. Most of the recovery occurs by 4-6 weeks. Soft foods for at least the first 2-3 weeks, then proceed slowly as you feel more able to handle chewier stuff. Most recommend to stay away from meats and bread, and I had difficulty with a raw carrot at about
3 weeks. (Started choking, despite lots of chewing couldn't wash it down with water, and threw it back up. Did not damage surgical site.)
Hope this helps.
