I am diagnosed with external anal fissure. Please let me know the remedy for this.

Hello doctor,

I was diagnosed with an external anal fissure. Initially, I was prescribed Hydrocortisone cream and Lidocaine or Nifedipine gel. This did give me some relief, but it did not completely heal the fissure. Later, I was prescribed the Ciplox-TZ tablet with the SN plus 15, along with Duphalac Fibre (a five-day course for tablets). This completely healed the fissure. This was six months ago. Recently, I have been experiencing slight trouble when passing stool and then some burning sensation in the anal area. This is due to a hard bowel movement. There is no blood in the stool, and I do not feel any fissures. Should I take one more course on the Ciplox TZ and SN Plus 15? I am currently applying the Lidocaine/ Nifedipine gel and taking Linzess tablet 30 minutes prior to breakfast (to induce soft bowel). Appreciate it if you could let me know the remedy for this. I have read that cow ghee is also a good option in addition to hot sitz baths.
