I have lower left abdominal pain, tarry stools (not black), sometimes hard stool difficult to pass. The pain is worse when I lie down and sometimes it feels like there is a spasm of the intestine, or whatever, in this very low area of my abdomen just above my pelvic bone. The lower left area is tender to the touch. It feels like menstrual cramps sometimes, but I am 5 years post menopause (55 years old). I have no fever or pain with urination. The particular symptom of lower left abdominal pain with spasm feelings started 6 days ago. The tarry stools started about a month ago.
