External hemorrhoids but painless.

I have a female friend who believes she has got external hemorrhoids. She use to eat spicy food a lot but recently she started feeling burning sensation at her anus and it became worse with time. She read online and found out that she had got external hemorrhoids as she saw it bleeding and felt a small bump(mole kind of thing) near her anus. From past 1 month she has been eating plain food without spices and she is feeling normal now as there is no burning sensation felt by her (while she eats plain food) but she still has that bump(mole kind of thing) near her anus. Any idea by when will it go off ? What is suggested here ? Any natural way to get this treated ? She still feels burning sensation if she eats even a slightly spicy meal.
