I had the same. You can get a cream to shrink it back, starts with p, cant remember the name but you need it to be prescribed anyway. And Obviously don't strain when you go to the toilet.
Procetoceydal (sp?) I have also used hemocaine - has a anesthetic in it.
Make sure you each lots of vegies/fruit, drink heaps of water and if need be get a fibre supplement. I found benefibre good cause it wasn't grainy. hope it gets better. xx
