Sir/ma'am I have a lump (painless) in perineal region, which is not visible from eyes or from surface. It's situated between interior thighs and anal region. After pressing skin I can feel hard jelly like mass . I can hold it well with two fingers when pressed hard . When I shake it , it sound like liquid but it's hard. No pain as such but sometimes discomfort in sitting. Stool is normal as usual, no blood , no thinning etc. What it can possibly be? Is it piles(interior)?
