Why is there no cream that "cures" them?

Germoloid, mayinglong, anusol hydrocortisone, why is there nothing that cures them? It just doesnt make sense that only surgery cures them. You would think with how common it is that there is a definitive non-surgical cure? Why do we have to suffer from this disease in current year?

The rectum/anus is so fragile, when you have a fissure you just use cream and pray it heals and same thing with hems? Why does the body not heal them? Maybe i need to do a 5 day water fast and not have a bm. Jusy don't understand why they don't go away.
