Okay so when I was younger every once in awhile I would feel pressure in my rectum area every time I sat down but then I would just relieve gas and it would be fine. Now, it is day too and I'm feeling pain and almost like pressure in my rectum area everytime I walk or sit on it a certain way. I have never had this for more than one day before or even for more than 30 minutes. Could this be sign of hemorrhoids? Not to be weird but I did check to see if I saw external hemorrhoids and there's no visible evidence there. So may this be internal hemorrhoids or a freak of nature gas problem? I have had no problems going to the bathroom or passing gas it's just not feeling better. I don't know if this has anything to do with it but I am 2 days late on my menstrual.
