For my anal fissure what kinda of natural ointment or cream would you suggest? I would like to try to heal before doing botox.

Nitroglycerine. Some patients repsond very nicely to nitro ointment.
Fiber and warm bath. First line therapy is bulking stools with fiber and water. Warm baths will sooth your pain. Second line would be a calcium channel blocker cream such as Nifedipine or diltiazem. Often these are combined with a topical analgesic like lidocaine. While Botox is an option, it has lower cure rate and higher recurrence rate than surgery which is the gold standard.
