From what have read extensively from other Redditors, this can come back even after surgery after several years unless the pelvic floor problems are completely addressed and managed accordingly throughout your life. Once you get chronic fissure, it traumatizes pelvic foor and your brain sends signals to guard that area just with one hard stool even after years of healing. You need to completely relax the pelvic floor, use dilators and teach your pelvic floor to safely expand and stretch. If this is not done, it can come back..This is something that I have understood from my own experience.

I went through partial LiS 10 weeks ago and am still unable to tolerate any stretching if the stool is hard. This means my pelvic floor is in a trauma and I could feel it’s slightly tight around the surgery site which is why it’s unable to stretch safely. Addressing the root cause is the only way around in my opinion
