hi, I had a severe case of constipation last night. I had not recently had any constipation and this attack came on out of the blue. I likened it to contractions when having a baby - these contractions came on and it felt like my insides from the waist down were pushing down, it took my breath away and made me feel quite fainty and hot. I could not pass any motions, although it was right down and I just couldn t get it out. I didn t know what to do, whether to sit, lie down or walk around. It was horrible! This lasted for nearly 3 hours when at last I was able to pass it. What do you think this could be?
