Today I had 6 bloody stools in a row (never happened to me before, ever!). I am recovering from knee bursitis, which hit me out of the blue one morning two weeks ago. I went to the emergency room and they determined it was bursitis. They said to follow up with my GP, which I did last Thursday. He drained some bloody substance from the knee last week and suggested I take Alleve, which I started 4 days ago. This followed a week of taking a prescription including naproxen after I had gone to the emergency room with the inflamed knee I woke up with. Are the bloody stools the result of the Alleve; or is the body ejecting more blood from the knee (which feels much better today) through my bowels (is that even possible?) as it heals? I also had adjuvant prostate radiation in spring 2015. I just read that blood stools can result from that years later. My number of daily bowel movements has increased since the treatment. I m assuming that the bloody stools will continue today every time I feel the diarrhea type cramp returning, as it has since lunch today. So far, I feel okay, with no dizziness or the like from loss of blood. Any thoughts and suggestions would be appreciated. Many thanks. (BTW, I am awaiting a call back from the nurse in my doctor s office now.)
