Hello, I am suffering from anal pain from past 3-4 weeks but no rectal bleeding or an anal fissure. Why pain is there. Is this an infection? Feeling fullness in my anus and redness is there inside. I do have constipation problem and 2nd degree piles but what's the connection with continuous anus pain while sitting and will start by evening. Some times legs are also paining after the rectalPain. Please suggest me what's the problem.
