I have and still am very constipated. I use stimulant laxatives so I can have a bowel movement. I have benn suffering from terrible pressure in my back passage for weeks now. I went to the gp today who examined my back passage but couldn't feel anything. I thought that I might have piles but haven't. I've been referred to the hospital for further test to find out why I have this constant pressure in my back passage. I'm not bleeding from the bottom at all and I don't have any abdominal pain. I'm just worried in case I've damaged my bowels from using the laxatives all the time or even worse I have bowel cancer
