M south indian. My doctor told me to put my butt inside a tub of hot salt water everyday for my piles (external haemorrhoid).How does it work?

Sitz Bath. Sitz bathes can be helpful. Sit in a bathtub with warm water. There needs to > be enough water to submerge the anal area. Soak for about 15 minutes – several times a day. An alternative is placing ¼ cup of witch hazel ; warm water in a basin. Soak for at least 15 minutes, at least twice a day.
