Its been a lot of time since I am having an irregular bowel movement. Also its not clear, I have to use lot of effort to push the bowel movement. I think i am suffering from constipation. Also their is a consistent itching in the rectal opening area which becomes severe in the night. As I am a bachelor and posted far from my home town, my food habits are irregular and not quite healthy at times. First I thought I was suffering from piles but there is no blood in my stool. My water intake is normal. I use to have a tablet for gastritis daily morning as quite often I suffer from a burning upper abdomen. As an info for you, nowadays I am taking tabs for allergy like allegra and cetrizine as recently only I suffered from about of allergy with hives all over my hands. This is the second time in my life that I had a bout of itchy allergy, first was in my childhood. I am totally unaware of what exactly cause the allergy but once I am attacked by allergy I can not tolerate dust and heat. Kindly hlp.
