My husband has been hving severe stomch pains when he awake, bad headaches, blood once in stool tired a lot can I please have sum ideas of what this may b?

See your doc. There are many things that can cause stomach pains, but with blood in the stool, it is time to see a doc. In the setting of pain and blood, i would be concerned for an ulcer or, less likely, ischemic colitis. Regardless, you need to see a doctor and possible even have a colonoscopy.
