For about a week I've been having this pressure sensation near my anus. It is not the anus itself but it feels like it's inside, possibly the rectum? It has become difficult to pass gas and I have a constant urge to defecate even if I already have. The pressure and pain gets worse if I sit down. My GI said it was constipation and gave me laxatives but even after taking them the pressure just came back. My stools are normal but I have been constipated a few times. Could it possibly be inflammation, or maybe a growth of some sort blocking it? Any help appreciated, I am a little scared about this.
Minor details, i am 22.
