I am a 23 year old male and am in the midst of a bout of diarrhea that started about a week ago. At about the same time, I started experiencing lower-back pain, extending into the left hip. I initially assumed it was a coincidence because I have frequently had lower-back pain in the past. Also, now that the problem has lasted over a week, I intend to consult a physician. Roughly every 3rd bowel movement includes a pink tinge to the softened edges of the solid waste as well as the toilet tissue, which I can only assume is blood.
Abdominal pain occurs only prior to and during bowel movements.
Once I realized the condition wasn't going away, I started eating more bananas and rice, but found it inconvenient to go on a strict BRAT diet. Back pain, focused in the lower vertabrae and left hip with stiffness in the left leg, makes it difficult to do certain activities without caution, viz. rolling over, sitting up from lying position, lying on my back. Pain seems to increase slightly during bowel movements, but this may be due to the lack of support provided by the seat. And I just discovered that I may be having trouble digesting parsley, as a recent movement left green leafy specks in the liquid part that are either basil or parsley from dinner. Hope this isn't too much information.
