Excessive vomiting, now bloody discharge and dark spots in stool.?

If you drank too much you probably hurt your bladder ...and sometimes whatever hurts your bladder ends up in bladder infection, and everytime I have a bldder infection I bleed a little, even a small hit in the lower abdominal area can cause an infection but you should go and see a doctor, it would be better. As for the stool...it can be related to your liver and kidneys....you should definetely go and see a doctor....also remember what happened last night...besides drinking...
