Hi' Dr. I Had Colon Surgery Aug2015, I Am 60,

Hi' Dr. I had colon surgery aug2015, I am 60, with a lot of health problems. I am obese, have controlled hbp, diabetes,Afib, on Elliquis, thyroid condition, OE. Also, kidney and bladder issues. 2 days ago, I felt a little tug, click ,in my abdomen, the next day it was very sore. Then, I've had bleeding bright red on 2 occasions with soft BMs. 40 % of my colon was removed. I did well. Could I be bleeding from the colon repair? a muscle tear? YYYY@YYYY . Thanks
