Bad Belly Ache With Sticky Mucus Acid Like Stool That Is Difficult To Pass

I desperately need to do something about the agony im in when passing stools. On and off for ages now but more often than not, i get a bad belly ache every time i need a number 2, my stool changes to an orange/yellow thick sticky mucus that is like passing pure acid, it burns so badly and although its soft and quite runny its harder to pass. To make matters worse i also have piles, 3 were from childbirth and weren't really a problem but now due to all this struggling to go for a number 2 i now have lots more inside aswell, making it even harder to pass this weird stool because it gets stuck behind them meaning more straining and then worse piles. Its a vicious circle and i can't carry on like it anymore, im finding myself trying to hold it in now which i no isn't good but i just can't stand the pain, my bum bleeds it feels like its inside out for a while after iv been. when my stool goes like it im on and off the toilet all day only passing little bits at a time, it gets more painful every time. Im waiting for a hospital appointment about the piles but i need to do something to help for now, its really starting to get me down. iv been having stomach problems for ages and now its all become one big problem what could be causing it? And is there anything i can do :(
