The need to go!

the past couple of days i have had the feeling that i want to go to pass a stool but nothing comes, im not constipated as i have been to the loo but i have a constant pressure feeling in my back passage. 

This is tenesmus. I hate to tell you this, but the dd (differential diagnosis) of tenesmus includes colorectal cancer. Have it looked at, because CR cancer is curable if caught early.

Thankyou

It could be cancer, but an internal hemeroid can also cause this feeling. If you have been somewhat constapated and have to strain to go this can swell up a roid and cause iritation of the nerves that signal your brain that it is time to go. It should be checked out but it doesn't have to be cancer. It can be, but I like to look at the brighter side. Try not to worry but get in to see a doctor, OK.
