So basically I had blood in my poo about 3 weeks ago it went and then came back so I went to see my doctor who gave me a rectal examination and said I had piles, I also suffered from a feeling like there was a tennis ball in my right side I told him he checked my abodomen and said everything was fine, after taking medication for piles (internal) the bleeding APPEARS to have stopped although I am still on the tablets and sometimes it s difficult to see, however the feeling in my right side is no better and when I strain there is like a swollen lump, I have the lump on both sides is it anything to worry about, I am 19years old
