Hi, I'm curious about a recent instance of blood in my stool. Over the weekend I had a continuing headache but yesterday evening, the blood concerned me when I went to the restroom. Today, my headache has gone away but I've been feeling dizzy most of the day, however, there was no noticeable blood in my stool this morning. I'm a 34 year old male, 175 lbs with no past medical problems other than being diagnosed with Thalasemia minor as a youth.
