It’s been around a month or so, I am having pressure on anus like I need to open bowels. Most of the time of day my anus is itching and scratchy. Heaviness all around lower back and abdomen. This heaviness is worse towards evening and night time. Bloated and tight stomach. Stools are not well formed, not complete always, but happens every morning. When I walk, after some time itchiness increases in my anus. I am vegetarian and have mostly home made food. Which is less spicy and less oily. My job is to sit and work 8 hours a day. Though I do take occasional walk and give rest to my back as well. Colonoscopy, Endoscopy says everything is normal. Please suggest something !!!
