29 y/o male, type 2 diabetic, high triglycerides, asthma. since last friday i have had lower abdominal/pelvic pain and have not had a normal bowel movement. Friday night i could not sleep with flu like symptoms (stomach ache, chills, body aches) but those went away. Saturday was painful, no bowel movement at all. Sunday through today the pain is slowly subsiding but still there and bowel movements have been very small, somewhat leaning towards diarrea. Appetite is fine, no major change in pain after eating. I get the feeling I have to go every so often, but nothing comes out and I dont want to strain too hard. Colitis?
