### input:
Hi, my name is Billie Hernandez. I have been dealing with an absess since August of last year. I have had it cut open 4 times. I had surgery November of last year they found 3 others one that have closed up. The first one they found is still open. It closes up and opens up over and over at times it just drains green, and brown pus. I have lower back pain with it and at times I cant eat also is very hard to walk and sit when it is build up. I sit in hot water to help it pop and drain. I have a new worry now when I feel like I need to go pee it hurts to push it out, also I when I need to go bm it hurts my back then when I go its very painful to go cause I feel like it s pushing on the absess. I fill like there is a build up right next to me rectal and I think that s what causing the pain. If you can help me to understand what is going on. I have colon cancer that runs in the family. Oh, yea I had loss bm for a day that was black I researched it and they said it s blood so know I am really scared on what s going on with me.

### output:

Hi, Thanks for writing in. Back pain can be due to many reasons from congenital disorders, trauma, infection and cancer. Since you have a history of abscesses and surgery, it is likely that your back problem might be due to the same reason. If colon cancer runs in your family then you should get screening investigations done. If you had black stools after having no stools for a day therefore it will be good to get an occult blood test done and also a colonoscopy if it has not been done in last 5 years. Please do not worry.
