Consider an experiment: try taking a break from sitz baths, as the positions you get into to do them may put stress on the area and re-tear the AF. Also what helped me: place bottles of water around you in your home etc. and carry water with you. Apply Aquaphor or generic Equate healing ointment nightly to the area, wipe with moist TP gently after bowel movement. Avoid exercise and motions that may re-tear the area. Two or three prunes per day, 2 (generic) stool softener capsules per day, avoid food that may constipate.
This worked for me- I felt MUCH better in less than a week, and a month later I could not feel my AF unless I sat directly flat on my butt for long periods. I still do these things above to keep reocurances away.
Best of luck! ..... believe me-- "I feel your Pain..."
