38 f. bowel movement with bright red blood. seemed like it was from a hemmoroid. my area hurt all day yesterday. what should i do?

Get checked: Rectal bleeding should never be assumed to be something. There is nobody that deserves less than the best treatment. This starts with a proper diagnosis.

Don't worry!: Your symptoms are quite likely from a small irritated hemorrhoid or perhaps an anal fissure, both of which should respond to soothing cream/suppositories, sitz baths and stool softeners to not further irritate the area. If it persists, worsens, get help and see your doc for a quick peek, reassurance and better options.
