Sure you can cure piles.
To cure piles naturally you need to change your diet and eat a lot of fresh fruits and vegetables and also to drink a lot of water.
You can also need to change some of your habits like - shorten your staying on the toilet.
There are great home remedies for hemorrhoids, do a little search in google and you
will find (you can find an example on the attached link).
I strongly recommend you to see a doctor to verify that you have piles and not something else.
