Because I live in a dormitory, I suffer from the fact that I can't go to the toilet during the day because of a big... frequency. I often have to hold it to go and, as a result of such tension, a blockage has already come out for two days... I don't know what to do... probably it's bad... It seems like it's still early... I'm very worried... And now I'm scared Is it dangerous if at this stage that a blockage comes out?
