It sounds like you have a hemorrhoid, which can be very painful but is not a problem you need to be worried about.
There are plenty of over the counter hemorrhoid creams which will help to resolve the problem over a 1 to 2 week period.
I would also suggest avoiding too much walking or exercise for a couple of weeks and changing your diet to include easily digested soft foods.
It is best to use water to clean up after a bowel motion rather than wiping until the problem settles down.
