It's quite embarrassing. I have a crack in my buttocks (right at the beginning). What should I apply to help it heal?

To help heal a fissure in the area of the buttocks, it is recommended to avoid activities that may irritate the area, such as sitting for long periods of time. Applying a moisturizing and barrier cream, like Prevex™, can also help with hydration and healing. If there is no improvement after two weeks of applying the cream, it may be advisable to consult a doctor.
